the first one is kinda fucking hard to flow, the drums are really weak, its kinda annoying, NEVER USE FRUITY LOOPS SOUNDS!!! download them at www.sf2midi.com they have some good soundfonts but imma say like Jett, you cant flow on it(Im talking bout the acoustic beat)

for the rock beat, this one is way better, but its way too repetitive, add a bass line or something, the drums are really weak again, now this beat its possible to flow on it

So dont forget to go on www.sf2midi.com and download some damn soundfonts

Peace
