did u try one of those file sharing programs....i hear they got acapellas. or buy a single of the song that you want the acapellas for. if im not mistaken singles have the song, the instrumental and the acapella....but i think thats only on vinyl.
thanks man, i didnt wanna have to go the kazza route and i dont wanna have to spend money on a record, maybe if i knew someone who dj'ed, but they would collect dust otherwise....thanks though
