Query: Humorous Rock - Cool CD

The one thing about the Barenaked Ladies is the light, humorous touch to their music. Even if the lyrics are serious, you can always expect alittle tongue in cheek humor thrown in for good measure. I really laughed through the song "Who Needs Sleep?", a song about the frustation of insomnia, but still sung in an upbeat lighthearted manner. The hits "One Week" and "Its All Been Done" are great lyrically and musically. Barenaked Ladies are refreshing and different.
