This has been brought up before, but I don't think in this exact way.

Would it be possible to implement a Mark for Deletion option so that when you hear a song that you want to delete off the empeg, you can mark it. Then, when you go into emplode and do a sync, it'll automatically get deleted. This would eliminate you having to do a search for marked tracks, and then deciding which ones you want to delete.

If people are worried about accidentally marking something for deletion, perhaps on sync it could pop up a verification dialog that says something like "The following tracks have been marked for deletion, is this ok?".
