Build a podcast soundtrack around one free song a day

A recurring podcast needs a few seconds of identity: an opening, perhaps a brief transition between sections, and a close. Buying or commissioning a new cue for each episode can add cost and coordination. A budget-conscious alternative is to draft music with StarSinger and edit the usable parts into an episode in Descript.

The boundary matters. StarSinger offers one free song a day, and its homepage says a song can be generated in about 90 seconds. That makes it a source of drafts, not a guarantee of a finished, broadcast-ready sting. The workflow also depends on being able to obtain an audio file and use it under the applicable terms. Check both before building the show around it.

Start with the recurring slots

Write down where music actually helps: the opening, a sponsor or segment handoff, a chapter break, or the ending. Set a rough duration for each slot before generating anything. A short intro may need only a few seconds; a chapter transition can be shorter still. The aim is to identify cuts from a song, not to ask every generated track to serve as a complete soundtrack.

Then decide what will sit under the host’s voice. Lyrics compete with speech, especially in a brisk intro. StarSinger’s catalog includes instrumental tracks, so an instrumental direction is worth trying for spoken sections. A vocal song may still work as a brief opening or closing, where there is no dialogue. Listen for that distinction rather than assuming any appealing song will fit every slot.

Use the daily song as a draft

Describe a track around the show’s mood and function: for example, a restrained, upbeat instrumental cue for a practical weekly interview show. StarSinger invites users to describe a song in one line. Keep the brief specific enough to guide the sound, but avoid expecting an exact duration or a clean edit point from the generation.

Audition the result against the show’s existing voice and pacing. Does the melody leave room for the host? Does the energy fit the opening? Is there a section that can end cleanly when cut short? Save a note of what works and what does not. One free song a day supports a steady drafting habit, but it does not mean each daily result will be suitable for publication.

The roughly 90-second generation time is useful as a draft checkpoint, not a promise that the track is ready to publish. That is the same distinction behind treating a 90-second song draft as a checkpoint: speed helps you test an idea, but it does not remove the listening and editing work.

Bring the cue into Descript

Before planning a recurring process, confirm that StarSinger makes the generated audio available in a file format Descript can use. The available product information describes song creation and music videos, but does not specify audio download formats. Do not assume that a track playing in the product can automatically be imported into an editing project.

If you have an importable audio file, add it to the episode in Descript and use the chapter cues to locate the transitions you planned. Put the intro before the host begins, and place a transition at a chapter boundary only when it helps signal a change. Trim the music to fit the slot. For music beneath speech, lower it until the words remain easy to follow; compare the result on headphones and ordinary speakers.

Make a short test export before using the cue in a finished episode. Listen to the join at the start and end of each music section, and check that a cut does not leave an abrupt fragment or swallow the first word after a chapter cue. Keep the original track and the edited episode project so a later change to the intro does not require rebuilding the whole soundtrack.

Keep the economics honest

StarSinger’s daily free song allocation and lack of a subscription can make this a low-cost way to develop ideas. It does not guarantee a free library of usable, cleared podcast music. StarSinger describes its plan as freemium, and its music-video products are separate from songs; a podcast soundtrack workflow does not need a video purchase. But check the current terms for permission to publish the audio, and do not treat a free generation as proof of commercial-use rights.

There is also a consistency trade-off. A new generated song each day may give a show options, but it may not preserve the same musical identity from episode to episode. If continuity matters, keep a chosen cue and reuse it only if the terms allow. Use new daily drafts to audition alternatives or develop a transition, rather than promising yourself a fresh, ready-to-air intro every morning.

The useful stack is simple: define the audio slots, generate and audition a song, verify that you can import it, then use Descript’s chapter cues to place and test short edits. StarSinger supplies drafts; editorial judgment, rights checks and final mix decisions remain with the producer.
