I'd like to see a new feature for Thumbprint Radio that includes songs from your My Thumbs Up Playlist.
For example, if hear a new song on youtube, I can look it up on Pandora, add the song to My Thumbs Up Playlist, then that song will play on Thumbs up radio.
Trying to add a specific song to thumbs up radio is very cumbersome at the moment.
I prefer thumbs up radio because I can hear new music based on my thumbs. The playlist doesn't have that feature.
