I think comparisons are inevitable in every line of creative work, after all that's how you know at what "level" you are. Sometimes there's not even anything in particular that you can point to and say "oh, THAT'S why that beat is better", It's just of superior quality overall, 30 levels above. I try to motivate myself too, but sometimes I just get tired, spending an entire day trying to make a beat sound half decent, then "comes" 9th, dilla, nottz or another cat and just shoves it in my face hehe sometimes it motivates me, other times has the opposite effect, making me think that i don't have the necessary talent to get there. Maybe it is what it is, some cats just got it flowing naturally.. what do you think?
