This is a very, very catchy tune. The kind that stays in your head and you hum at 2:00 in the morning. I like it a lot.
A couple things:
1. I would be interested to hear this with different basses. Nothing wrong with the current version, but just to compare.
2. To build a little expectation for the listener, It might be interesting to not bring the bass in until about 35 seconds into the tune, or maybe have it play the first 15 seconds (intro), drop out, and then back in at 35. This is just a stylistic thing, not a critique. Great song!
