The End tag gets surer every year on no new evidence

Your song will not stop. It fades out, or it runs to 7:59, or it sings the last two lines four more times while the credits drain. You go looking for the fix and the guides agree: add [End].

Then you try to find out where that agreement came from.

Suno does not publish a list of tags

Suno's help centre has a music glossary. It defines verse, chorus, bridge, pre-chorus, intro, outro, hook, refrain, break and drop, as words, the vocabulary you use when you describe music to a model. It is not a syntax reference and it never uses a bracket. The help article about writing prompts inside the lyrics box, the one that shipped with v4.5, tells you to add more context there and names no tag at all.

We checked again on 11 September 2026, two days after Suno replaced every earlier model with v6. The v6 FAQ and the page on what is new in v6 describe the models, the editor and the credits, and neither lists a single tag.

So there is nothing to check a tag against. Every tag list in circulation is community work, which is fine and often good, but it means the guides are checking each other rather than checking the product. [End] is the clearest case of what that does over a couple of years.

The wording gets surer every year

The earliest version I can find is a tag dump posted to r/SunoAI in March 2024, back when the model was still called Chirp. It carries six different ending tags: Big Finish, End, Fade Out, Fade Out and End, Fade to End, Finale. Six candidates for one job is what a field looks like before anyone knows the answer. The note beside them says an end tag may work best alone in its own clip, which is a suggestion, and the list's own header warns that the model tends to have a mind of its own.

Two of the most-copied lists from that same spring skip the tag entirely. The April 2024 post titled simply Suno AI Tags, which is where a lot of the later guides got their vocabulary, has no End in it. The Suno Wiki's metatag list, a month later, has no End in it either.

By November 2025 it has stopped being a candidate and acquired a definition, "a defined, clear ending", which the list adds is often abrupt or dramatic.

A metatag guide from April 2026 goes further: the tag "explicitly marks the end of the song" and "helps cut off cleanly". A guide updated in August 2026 goes further still and calls it a hard stop that prevents trailing audio.

May work best, a defined clear ending, helps cut off cleanly, a hard stop. Four steps, each surer than the last, and not one of them plays you a song.

The people who tried it do not agree either

The thread where people go when a song refuses to end is full of attempts, and the striking thing is that no two of them are the same fix. One writer presses enter twice around the tag and puts their success rate at 95 per cent. Another writes the tag with a row of dots under it and says the dots are inaudible but it mostly works. A third gets nothing from any of it and closes the song by hand outside Suno.

That is not a body of evidence, it is a set of personal rituals, and every one of them is honestly reported. Nobody is lying. They each found something that worked once and told you about it, which is how folklore starts in a field where the vendor documents nothing.

None of this is a reason to leave [End] out. It costs nothing to type. It is a reason to know which of the tags on your sheet are doing work and which are there because a guide sounded certain.

Three questions before a tag costs you credits

Is the word in Suno's own vocabulary? Outro is in the glossary. End is not. That does not make End useless, but it does mean the model has been described one of those words by the people who built it and not the other. When a documented word and an undocumented one compete for the same job, spend your generation on the documented one.

Was it in the oldest lists, or does it only appear in the new ones? A tag that shows up in 2024 and is still there in 2026 has survived two years of people trying it. A tag that appears only after the guides started copying each other has survived nothing.

Has anyone shown it, or only said it? This is the question that does the most work and the one almost nothing passes. A demonstration is two generations from one sheet, one line apart. Generate this:

[Chorus]
I tell my sister I am fine
I tell my sister I am fine

[Outro]
The dryer stops

Then generate this, changing nothing else:

[Chorus]
I tell my sister I am fine
I tell my sister I am fine

[Outro]
The dryer stops
[End]

Then listen to how each of them finishes. That is all it would take, and across six guides and the threads behind them, nobody has posted it.
