Dude, this could be bigger than most of the rest of that shit submitted on audio newgrounds. Go right now and submit it everywhere you can. youtube, last fm. generate some publicity. Dont listen to these people saying that its not that good. Take your good song and run man, you probably could make into a famous song. Just add a bridge, maybe some more verses and change it up a little more but great anyway. Maybe add a stand up base or a cello to get that background sound that nirvana unplugged had. I think it work pretty well. Drums may or may not be good but definitely try to incorporate some sounds or instruments, just to spice of the verses and give it more depth. I know you like the intimate sound of just you and the guitar but try it and see if it sounds good. Great voice, great chord progression. Frankly, im jealous, i wish i could write shit like this. Nice job once again.
