Influenced in bits and places by bands like Rise Against, Underoath, Ruiner, Defeater, and Verse (although some of these influences won't be as apparent).

Wrote it during this month, I'm thinking of recording it with vocals to enter it into the 30 day song challenge.

It's a very simple song, not very long either. Just looking for advice on how to make it a little better.
Hey what do i open it with? I tried Guitar Pro, Windows Media Player, and Audacity...
