I like the idea of "mark for attention" showing up in Emplode somehow. But subsequent presses of Mark could do things like add to favorites list. Will the "mark for attention" place the song in a playlist in emplode? If that's the case, it might be easily customizable so that you could have any number of playlists to which the track would be placed.

I really want to have an easy way to build a favorites playlist on the fly and factor that into a custom shuffle mode. In reading the other threads about shuffle customization, it doesn't look like you can select from a given playlist yet, so this would be very welcome as well.
