Barenaked Ladies is a band that you either like or you hate. There is no way around it, they have a way of polarizing people. I am a fan of them.
That said, Maroon is by no means BNL's best CD. It is loud, doesn't give Steve Page a chance to use his voive, and most of the songs sound the same. For classic BNL, I recommend Rock Spectace.
However, Maroon is also a very good CD. The lyrics are jumpy, fun, and humorous, and Steve has one of the best voices in music. Highlights include "Sell, Sell, Sell" about commercialism in Hollywood, "Helicopters" about a musician's reactions to war, and "Tonight is the Night I Fell Asleep at the Wheel" because it is just plain weird.
If you are a fan, buy this CD, if you are not, borrow it before you buy.
