OK, so just one idea for now but I hope to add more as time goes by.
1. Have the song page where you can stream the jamendo (or other) tunes from pull in and show the lyrics (if any) from the corresponding jamendo page. See:
Lorenzo's Music - it could be you - libre.fm page
Lorenzo's Music - it could be you - jamendo lyrics page
It would be nice to be able to see the lyrics while the song is playing.
