They sound great really, but I think it would make a very unconentional mix.
It does seem like it could potentially make an unconventional mix, but in practice the two blend together beautifully. Keep in mind that the music is intended as pure ambiance, and it'll usually be playing at a relatively low volume compared with sound. We'll be releasing several game play videos with full music including transitions pretty soon to demonstrate exactly this.
