We need an option to automatically add to Collect and option to autimatically add to a specific playlist (I only have 1 playlist, so both would be great options). Even if I hade multiple playlists, I would concentrate on 1 genre/playlist at a time as a general, and I'd bet the the majority does the same.
Option to automatically add to Collect is because that feature is the only way to Sort - which you don't have - and the only way to reasonably check for duplicates - which you don't have. Why do we need to waste time clicking multiple times when we would automatically want Collect and Playlist "Favorites" EVERY time???
