Good stuff.
I like your songs. I hear a lot of different influences, and styles here. Reminds me of early Death Cab for Cutie, Explosions in the Sky, or Pedro the Lion. I could go on through a list, but this music still sounds like its coming from somewhere origional, so thats all that matters. Myspace tends to be a bitch to get working correctly, but once it finally played the songs, I enjoyed them. I have the same problems every time I listen to anything on there. I use it the same way you do though so I understand how great of a platform to put your music on, it is. You may not wish to add any vocals, but I think it would add a lot to them. Its still good the way it is, but I say experiment with something. I hear Badly Drawn Boy-style vocals all over this in my head. Keep posting those songs, I'll check back often.
