sorry...
That's incredibly weak...
It's soooooooo damn easy to find a real dj that would probably do it for free too, if he gets his name up etc...
I understand your logic of it, but it's not real!
It's biting someone else's work, hiphop's about being authentic...would you use an already made beat, and use it for yourself, I'd hope not.
If all you want is simple scratches, It's real easy, any one with tables could prob fill your kwota...unless you were looking for some Q-bert or something. I don't mean to blow up on you, your not the only one who has thought to do this or has done it, beleive me, but to me this is the apitemy of shame to the music.
your doing a video right, so it's not really music, but atmosphere to the video...I'd just ask an artist if he'd be down to rep his shit on a video, if it's low budgy I don't think any artist would try and make money off you, or even if it wasn't they might get their music heard by a new audience etc... I could see many artists letting you use their scratches if you just asked and told them what you want, then you could actually say on the video that you got a real dj to do your shit, and it will look more impressive.
better than some kid looking at it wondering who did it...
but if you just take the singular scratches and sort of cut and paste your own stuff, I guess you could get away with it. I just wouldn't copy anything long enough that your stealing the artists talent.
