Hi Jeff!
A few times, it sounded like you weren't feeling so hot, for your vox - maybe a cold, or something? I think it actually works with the song, because a little bit of raspy goes with the lyrics of a partying, up all night, guy. I liked the whistling part, too. I read the prev comments, and found that there was someone who didn't like it, but I was already planning on writing to say I did!
Glad to hear your puter got all fixed back up.
I think you've worked through your issues from the previous comments, but I noticed a bit of background movement going on right at the end, just before the last guitar strum. Don't know if that was intentional.
I'm always amazed at the very large music you create all by yourself.
