I just played this pack on guitar and harmonies, and it's pretty cool. The guitar part on The B--- is back it's pretty fun, not awesome but cool. The harmonies are fantastic. I don't particularly like The B--- is back but it turned out to be really good, while Don't Let The Sun Go Down On Me is really great. Probably as lowlander said, the worst thing is that it does have a lot of empty moments, but the rest is great. I guess it's the closest we'll ever get to Beatles in RB3 in terms of vocal structure and melody.
