Prince is releasing a three-disc CD set through the retailer at the end of this month. The set will include two new albums — “LOtUSFLOW3R” and “MPLSoUND” — as well as a third by his new artist, Bria Valente, for the price of $11.98. Prince is just the latest music legend to release new music exclusively through a major retailer. AC/DC and the Eagles were among the acts who sold millions of CDs through their partnership with Wal-Mart. Prince has released his recent CDs through major labels, but they were one-album deals that gave him the flexibility to go elsewhere when the project was done. The CD set will be on sale at Target and its Web site on March 29.
