Love it man, it has a really cool feel! The vocals have a good gritty quality, and they contrast with the upbeat quality of the instruments really well. It seems like the songs are missing a little bit of originality between them, but there is beauty in their simplicity. I think if you worked with different instrumentation or rhythmic patterns in the song it could add that extra layer it (in my opinion) needs. I like Round With Rhythm a lot, that's my favorite of the group.
