This was my first John Mayer album, purchased in January 2004. I'm a guitarist, and read about this guy in several guitar magazines, so I thought I'd give him a listen. I'm *very* glad I did... this album is full of great songs - several with some common melodic content, for sure, but each track is nonetheless quite different than the next. My particular favourites are "My Stupid Mouth" and "Your Body Is A Wonderland" - both brilliant tracks, but the rest are great too, with only one or two that don't quite inspire me. I've heard people say you need to listen to John's albums a few times for them to fully grow on you, and based on my limited experience I'd agree. This isn't guitar pop of the 3-minute-easy-listening variety... there are pop, jazz, rock and folk influences in here, as well as some very clever lyrics, not all of which are obvious the first time around. But after a few trips through this CD from start to finish, I find it's now one of my most played albums. I recommend "Room For Squares" unreservedly.
