Beat Fights! is a one-on-one beat battle featuring IllMuzik members. Each battle is posted on YouTube, where anyone can vote at the end of the video. IllMuzik members can also vote in the forums.
You can use whatever sounds you want, synths, just remember to read the rest of the restrictions. What we are looking for is originality, creativity, mixing skills and overall dopeness!
You can have samples in your beats but just keep in mind that YouTube might flag it for copyright, which means it may be a problem. So if you're using samples, try not to have your sample be so obvious. Chop it, add effects, just don't keep the sample in its original form.
