Scott, Although I could not get the tracks to play from that link directly for some odd reason, I searched for you on iTunes and checked the music out.  You did a good job and this is a good production.  And, you definitely have an identifiable style which is important.
 
I have sold on other sites instead of iTunes because of the expense differential; however, at this time, someone who is not on iTunes does not exist for a good percentage of music buyers so I will sell my next CD there (as well as my own website and other outlets).  I also produce a rock band and the credibility of iTunes is important.
 
Perhaps a tutorial on on to set up and sell on iTunes would be a good thing for the Forum members.  Some of us would probably send you a small donation in gratitude.  Of course, if a dummy site already exist with the steps laid out, maybe you could share that.  I remember years ago going through this on bar codes.  Turned out to be easy but no one knew where to point me at first.
 
Good luck.
