Just to make sure it is clear, Fandom is not Wikipedia. Wikipedia is a single wiki that has pages on a large variety of topics. Fandom is the name of a hosting service that hosts thousands of wikis. Each wiki has its own specific topic. If you want to post information about a musician, search to see if there is a wiki about that musician, their band, the music company they published with, etc. Those wikis would be the appropriate place to publish that information. If you tell us the name of the musician, we might be able to help you find the correct wiki.
