It would be cool to be able to leave comment tags on your cue points/anywhere in the song so that you can label choruses, breaks, bridge, main vocal.

As you see the track playing you can see the comment pop up, ex: "4 more bars till break" or "get ready to drop acapella". Kind of like sound cloud when people leave comments on certain parts of the tracks/songs.

Very handy in a situation where you want to work quickly when cueing through track for a specific part of the song; or if you or someone else are using someone elses library and you're not familiar with their specific mixes of the song.
