How Long Should an AI Song Be?

Song length is a creative choice before it is a technical one. A wedding reel, a YouTube release and a morning aarti all want different lengths, and the right one is whatever fits how people will actually hear it.

This guide gives a practical length for each common use, explains how length works on Autunes, and shows how to trim a song once it is made.

Use these as starting points, not rules.

Short video rewards a fast start. Viewers decide in the first moments whether to keep watching, so lead with the strongest part of the song, usually the chorus, not a slow intro.

On Autunes, short-form audio is made for this. Choose 15, 30 or 60 seconds (depending on the template) for 2, 3 or 5 credits. Alternatively, make a full song and trim out the best 30 seconds. If you plan to use a chorus as a reel hook, write it as a short, repeatable line so any slice of it works.

There is no hard rule, but the mainstream pop norm sits around three minutes, give or take thirty seconds. Ballads and Sufi songs often run longer; rap and dance tracks can run shorter. What matters more than the number is that the song keeps moving: a new section, a lift in the chorus or a bridge every so often.

One widely known detail: Spotify counts a play as a stream once it passes 30 seconds, so an intro that drags past that point gives listeners a reason to skip before it counts. Get to the voice or the hook early.

These are driven by the slot, not musical convention. Write to the exact length: a 30-second ad needs a song that says its one line and ends cleanly, not a 3-minute song cut off mid-word. Short-form audio on Autunes lands at the exact length you pick.

For background beds under a video or a presentation, an instrumental is usually better. Switch on Instrumental Only so there are no vocals competing with the voice-over.

Songs run up to 3 minutes on the Free and Pro plans and up to 5 minutes on Creator. Within that limit, length mostly follows what you write. As a rough guide, a sung line takes around five seconds, so 20 to 32 lines fits comfortably in three minutes. Write two verses and a chorus and you get a short song; add a bridge and a final chorus and it grows.

If you are on Creator and want a four or five-minute song, write enough lyrics to fill it, and listen through to the end to make sure the vocal carries the whole way. A long song with too few lines has long instrumental gaps.

For very long texts there is Long Forms, part of the Creator plan. It takes 70 to 140 lines, such as a full chalisa, aarti or qawwali, and builds one piece of up to about 12 minutes for 30 credits. Texts under 70 lines sing better as a normal song.

On Pro and Creator, two quick tools help you shape length after the song is made. Crop keeps a time range, such as the 30 seconds around your chorus, with an optional fade, for 1 credit. Cut, in the song editor, removes a section from the middle, such as a second verse, joins the rest with a short crossfade and saves it as a new track, also for 1 credit.

On the Free plan, the simplest route is short-form audio at the length you need, or trimming the downloaded file in any video or audio editor.

These are the ones that cost the most time.
