Query: Two very good songs but the rest is mediocre

This album is not under rated. The songs "Angie" and "Doo Doo Doo Doo Doo (heartbreaker)" are very good indeed and might be a reason to get the album, but the rest of the material isn't anything to get excited about. Of course "Exile on main street" is a better buy than this one. It's not really bad or really good - it's more or less a decent or average Rolling Stones album that you can either have or lose.
