Add me to the list, I think it’s a cool track, too. Your playing is great, as well as the tones and the general mix. I also think the drums are the weakest element, but like the others said, I don’t think they sound bad, either. To me, it sounds like you’re using virtual drums (as do I); if so, they don’t sound as good of “quality” as your other instruments. When I’m mixing my virtual drums, I take a lot of time to make them sound more natural by playing around with the velocities and sometimes nudging the timing just a tiny bit here and there so they sound less artificial. Also, using a very high quality drum sample library helps. It’s a pain in the bum sometimes, but it helps. All that said, I can’t see AJ rejecting this song because of the drums…
My only guess (and a best guess is all we can give around here) is that as far as the composition goes, it’s a bit repetitive. When you have a song form like an ABABA, for example, every time you come back to the A section, I’d add a little something different so it’s not just an exact repeat as before. You could keep the first A section pretty basic, and then the next time you come back to it, change the melody, or add to it. And maybe the second time you could add or change a harmonic element… Just change it up a bit, but don’t go too crazy. Beyond that, I don’t think it was too “band-ish” or “artistic.”
I just had a piece accepted a week or two ago that I thought wouldn’t have a chance… I thought it would be a bit “too much” for AJ, but they approved it. So who knows???
I’d say tweak it a bit here and there depending on what you feel it needs (take or leave anyone else’s suggestions), and resubmit it (I got another piece approved doing that as well). Good luck!
