How about editable playlists? Allow users to make suggested revisions and additions, letting a playlist evolved without the OP...

I've longed for someone to do it... something akin to StereoMood with a little bit of TurnTable.fm activity to it.

What do you mean by editable playlist? Are you suggesting to let users update each other's playlist?

My app will have a global song database with emo-tags(user generated) attached to songs. It will let user maintain their own playlist, import songs from other public playlists or site's global playlists.

Yeah, community playlists. StereoMood sort of does it... I think more with tags, like you suggest.

I always want something me and my music nerd friends can play with and share. Like keep a playlist going in the office but let any people add to it.

Google Docs for playlists?

Group Playlists - A playlist maintained by a selected group of friends. :)
