Most campaign videos sound the same because most of them use the same stock music. Teams spend weeks on messaging, visuals and targeting, then drop a generic track underneath at the last minute. The result is content that looks on-brand and sounds like everyone else.
An original song changes that equation. When the music carries your own message, in your own words, it becomes part of the campaign rather than wallpaper behind it. Until recently, that meant hiring a composer, a singer and a studio. Today, a marketing team can turn approved campaign copy into a sung, fully arranged draft in an afternoon and decide whether it is worth taking further.
This guide covers when an original song makes sense, how to write lyrics that work for marketing, how to produce a draft with AI and how to measure whether it earns its place in the campaign.
Not every campaign needs a song. Short ads and product teasers are usually better served by a jingle or a sonic logo of a few seconds. A full song makes sense when the content is long enough for music to matter and the message benefits from emotion:
Product launches with a hero video, event stage moment or launch livestream.
Brand anthems that express what the company stands for, used across a season of content.
Social video series, where a recurring theme song ties episodes together.
Events and trade shows, where a song can open a keynote or loop at the booth.
Internal campaigns, such as onboarding videos, sales kickoffs and culture content, where a song is memorable and a little playful.
The common thread is repetition. A song pays off when the audience hears it more than once and starts to connect it with you.
The advantage marketers have is that the message already exists. Positioning statements, taglines and campaign copy are the raw material for lyrics. The work is translating them into something singable.
Make the chorus your core message. The chorus is the part people remember, so it should carry the one idea you want to stick. Keep it short, rhythmic and repeatable. If your tagline is easy to say out loud, it may already be most of a chorus.
Use verses for proof and story. Verses can describe the customer's problem, the moment of change or the outcome your product delivers. Concrete images work better than feature lists. "Inbox at zero before the coffee's gone" sings better than "automated email prioritization".
Keep the brand name singable. Say it at the tempo you imagine. If it is long or unusual, place it at the end of a line, where the singer can hold it, and spell it the way it should be pronounced.
Leave out what belongs on screen. URLs, prices, promo codes and legal lines do not belong in a lyric. Put them in captions, end cards or the voiceover.
Get the lyric approved before you produce anything. Treat lyrics like any other campaign copy: route them through the usual brand and legal review. It is much cheaper to change a line on paper than to regenerate a finished song.
AI song tools that work from your own lyrics need clear structure to place the hook in the right spot. A few conventions help:
Label the sections, for example [Verse], [Pre-Chorus], [Chorus] and [Bridge]. The labels guide the arrangement and are not sung.
Paste the chorus in full each time it returns. Writing "repeat chorus" is ambiguous.
Keep production notes out of the lyric field. Genre, instruments and mood belong in the style settings, otherwise they may be sung.
Match line lengths within a section. Similar line lengths produce cleaner melodies.
Aim for a realistic length. Two verses, a chorus repeated three times and a short bridge is roughly a two-and-a-half to three-and-a-half minute song, which is plenty for most campaign uses.
Once the lyric is approved, the production step is quick. With a tool like Lacuna, you paste the approved copy and turn your lyrics into a song with a sung melody, an AI vocal and a full arrangement. You choose a sound direction, such as a pop anthem for a launch or an acoustic ballad for a customer story, add optional style notes and pick a female or male vocal, or let the AI decide.
A few practical tips from a marketing point of view:
Generate more than one direction. The same lyric as an upbeat pop track and as a cinematic piece will feel like two different campaigns. Put both in front of the team.
Use a model that follows the words closely when wording is approved. Some models interpret phrasing loosely to fit the melody. If legal has signed off on every word, choose the option designed to keep lyrics as written and listen for any changes.
Compare takes with the brief in hand. Does the chorus land on the core message? Is the brand name clear? Does the mood match the audience?
Keep every version. Stakeholders often change their minds after hearing the alternatives. Having the earlier takes saves time.
Most tools of this kind let you start free with monthly credits and listen to every version, with downloads and commercial use tied to paid plans. That makes it easy to test an idea before asking for budget.
Original does not automatically mean cleared. Before a song goes into paid media, check three things:
Rights to the lyrics. If an agency or freelancer wrote them, make sure the contract assigns the rights to your company.
The tool's commercial terms. Commercial use usually depends on the plan you are on. Some tools also provide a license agreement for each track on higher tiers. Keep a copy with the campaign files.
Voice and likeness. Do not ask an AI tool to imitate a real, recognizable singer. Use the tool's own vocals and avoid anything that suggests an endorsement you do not have.
Document which version was approved, when it was generated and under which plan. It will save time if anyone asks later.
An original song should be judged like any other creative asset. A few ways to measure impact:
Video retention. Compare average view duration and drop-off points against a version with stock music.
Engagement. Watch saves, shares and comments that mention the song or quote the lyric.
Recall. In post-campaign surveys, ask whether people remember the tagline. A sung tagline often scores higher than a spoken one.
Conversion. On landing pages and lead-capture videos, A/B test the song against your usual track and compare sign-up or demo-request rates.
If the song wins, reuse it: shorter cuts for social, an instrumental version under voiceovers and the chorus as an audio signature at the end of every video in the series.
Marketing teams already own the hardest part of a song, which is knowing what to say. Writing that message as a lyric, structuring it clearly and producing drafts with AI turns a costly, slow process into something a team can test in a day. Start with one campaign, measure it honestly and let the results decide whether original music becomes part of your playbook.
