I don’t normally listen to much pop music, so I know I’m a bit late to the party on this one. But I’ve noticed that in modern pop music, artists will sometimes release a “normal” version of a song, then a few weeks later they’ll release the same song again, except one of the verses is replaced with a feature. It’s not a remix, it’s just the same song but with another artist singing some different lyrics.

Is there a name for this type of song? How long has this been going on? When was this trend started?
