Do I have to sing/rap for the whole song?

Per our Release Policy, when you create a song, your vocals must cover approximately 75% of the track. This means that, yes, you have to sing or rap for a majority of the track. 

Songs submitted to us with little to no vocals are not considered valid releases, and will be rejected. This is because everyone has to equally contribute to the track; the producer provides the instrumental/beat, and the artist provides the vocals.
