Prince doesn't use a record label so you are not going to see the same level of promotion that you do with other artists. However, he manages to garner half-way decent sales because of his die-hard fan base. LotusFlow3r/MpLSound narrowly missed a #1 debut to country artist Keiith Urban and is probably Gold by now. I'm assuming more of the proceeds actually goes into his pockets since there's not so many record company execs with their hands out ready to collect from someone else's creation.
