Death Cab for Cutie; don't let the name fool you. This isn't another angry band, or another angry rapper.
Their music is really just poetry put to tastefully made music.
There is no mention of drug use or alcohol in their songs.
Most of their songs are about young love, music itself, and everyday life.
The lyrics are good, and unoffensive. The only exception to this would be in their song "Styrofoam Plates" where the song is talking about a father who abandons his wife and kids. The songs ending lines consisting of the words "he was a bastard in life, thus a bastard in death".
All in all, a good band for any age and enjoyable by just about anyone who likes music.
