'Heavier Things' is, in my opinion (of course) a much 'smarter' album than 'Room for Squares' in all respects. Musically it is deep, textured and heavily appealing. Lyrically, it's a BIG step up from his first album. Much less 'teeny bopper' and much more wit and depth.For all of you complaining about his more diverse usage of instrumentation, I question your understanding of music production. The guitar riffs are exceptional here, but the additonal timbres of other sound sources (both organic and electronic) really compliment and 'round off' his sound.This album is tight, warm, clean, smart, deep and WELL worth many listens. Buy it.
