YouTube singers from time to time will host group competitions, so called YouTube chorus battles or duet battles, in which singers will be able to submit an entry, which will then be judged to determine whether they get into the next round or not. Sometimes prizes, such as an illustrated PV or an original song, are offered to encourage singers to participate in the battles.
