C'mon dude, this wasn't shitty at all, in fact it was pretty solid. I will say that I agree with the one friend who said it wasn't quite "you," more so with the vocals. That's not to say they were bad, because you have a great voice. I think it might've been the overall tone that felt different. I feel that 'Love Burns' had your strongest vocal performance (I know it had autotune but that's besides the point). The feel was more intense and focused. It could've been like your other friend said, how the vocals were blended into the background a little too much, and that's why they felt softer here. I dunno, either way it was a good song, so well done sir :3
(Also, I totally get the shy-artist-around-other-people thing, cause I've got it too haha)
