I heard a very cool song recently and couldn't tap my toe to it without noticing that it's not in the typical time signatures. I had to search it to hear it again and found that it was Radiohead. I always liked them, but I guess I forgot that they exsisted... and that they were very inventive with their music. The song 15 Steps from the In Rainbows album is awesome! It's got a great driving beat, but it's in 5! I'm a sucker for individuals in a sea of poser-faces. Love it! Go listen for yourselves.
