I agree with caine man, you shoulda put more effort into this, if u did woulda been siik!!!
I give it a 4/5, 8/10..Keep practising with the vocals and trust me u'll get there, you have a voice which can be used perfectly for rapping man :)
However, I do agree with T-Free. It's not anything that you have to fix by re-recording the vocals. I could hook your vocals up if you're cool with sending me the track and your acapella. If you're cool with that, then you could PM me.
can i have your IM addy for Msn or whatever?
I think the voice does not sound powerful enough, you should put more action into it and make it more emotional. But altogether it's quite nice, keep it up.
