For a track to be accidentally uploaded on streaming services and a playlist it would have to be the a hell of an accident, because it's something that take several steps to happen. They would also have to cut out the final chorus by accident.

You have this person who picks up a music file that isn't named as a finished track, upload it, give it a cover, keep the file's unfinished track name after uploading it and after all that picks the same unnamed file and put it on a playlist that already existed. And even if the person has done all that, they never notice anything unnusual about it.

Seens very likely.

At least had the track a proper title it would be kinda dubious.
