I must say that just listened back to the Jonas V/liVe tracks and there were some true pop gems there, beside that Pom Pom song, which should have stayed in a vault
All tracks from that "era" could have been good solo tracks for either both Nick and/or Joe.
Who I Am is def. not a bad album and I love that kind of music, but I guess I find his voice a bit too whiney on it. He grew a lot since then, his voice matured more and the times he gets more whiney, it fits imo.
