I'll admit, I'm late getting into Modest Mouse. I knew they had a few albums out prior to hearing "Float On" on the radio, but I had to rush out and buy the single when I heard the song.
"Float On" reminds me of something the Talking Heads would have recorded in their prime. It's very catchy and upbeat, with a cool guitar riff and chorus that I often find stuck in my head all day.
Although "I've Got It All (Most)" is not as stellar, it's still a very strong track. If you own the full-length album ("Good News For People Who Love Bad News"), you could probably compare "I've Got It All (Most)" to the album's "Ocean Breathes Salty." Actually, the song is good enough to have made the album, but since it didn't, I'd recommend spending a couple bucks to have it.
