This tends to happen more often. I started to make play lists of my favorite music. As I listen to an album, it would be great to be able to check the song(s) and select in the drop down "Add to Playlist...". This would bring up the lists of play lists. I could then select to add a the selected song(s) to that play list.
The process to do this now requires a bunch of steps which involve stopping the music (loading the play list, selecting album again, adding new song and re-saving the list again...).
What do you think about this feature?
