Original vs Library Music for Advertising: What Every Brand Should Know

When a brand commissions music for an advertising campaign, one of the first decisions is whether to use original composed music or a library track. Both have their place. Understanding the difference — and the trade-offs — will help you make the right call for your brief, your budget, and your brand.

At Reseda Studio, we compose original music for advertising campaigns for clients including Mediaset España and Atresmedia. We also work alongside agencies navigating this exact decision. Here is an honest comparison.

What is library music?

Library music (also called stock music or production music) consists of pre-recorded tracks available for licensing from catalogues like Artlist, Musicbed, Epidemic Sound, or major publisher libraries. You pay a licensing fee and receive the right to use the track in your campaign.

The advantages are speed and cost. For a short social media campaign on a tight deadline, a library track can be cleared and in your edit within hours. Costs are typically a flat fee or subscription.

The limitations are exclusivity and fit. Anyone else can license the same track. And unless you are very lucky, no library track was written with your campaign in mind. You are finding music that is close enough, not music that is exactly right.

What is original commissioned music?

Original music is composed specifically for your campaign from scratch. The composer works from your brief, your edit, your brand values. The result is music that fits your visuals precisely — in timing, mood, tone, and message.

The advantages are fit, exclusivity, and ownership. No other brand will use the same music. The track can be composed to hit specific moments in your film. You can own the copyright entirely or negotiate a buyout, removing ongoing licensing concerns.

The investment is higher, both in budget and time. A typical advertising composition project takes two to four weeks from brief to final delivery, depending on complexity.

When does original music make sense for advertising?

Original composition is almost always the better choice when the music is central to the campaign rather than background texture, when the spot is high-profile (TV, cinema, large digital spend), when brand consistency requires a distinctive sonic identity, when you want to avoid competitor brands using the same track, and when timing and sync to specific visual moments matters.

Library music works well for lower-budget social content where speed matters, internal communications and B2B content, content with a short shelf life, and situations where the music is truly ambient and non-distinctive.

The hybrid approach

Many campaigns use both. A hero film with original composition for TV and cinema, and library tracks cleared for cut-down social versions. This balances quality and budget effectively.

What does original advertising music cost?

Pricing varies significantly based on usage rights (broadcast versus digital), duration, number of deliverables, and whether you want a full buyout. At Reseda Studio, we work across a range of budgets and can discuss what is realistic for your campaign.

The key question is not “can we afford original music?” but “what is the cost of music that does not fit?” A spot that looks right but sounds generic rarely performs at its potential.
