I've just bought this album for a friend who asked me who Josh Groban was! She will love it, as it's a great introduction to his style, & his available albums.
For me, who owns most of his albums already, the only interesting 'new' material is the live 'Anthem' from 'Chess' which is great, a live version of 'Weeping' with the Soweto Gospel choir, also good, and 'Smile'. As I already own 'Noel', Josh's Christmas album, the bonus CD doesn't really count, especially as my favourites from 'Noel' aren't included.
Fabulous at the price, & I'd have bought it anyway!!
