Musicology quickly proved to be Prince’s most successful album since Diamonds and Pearls, reaching the Top 5 in the US, UK and Germany and making a significant impression on charts around the world. It also proved to be well received by music critics. The title track was only released as a single in Australia, where it enjoyed moderate chart success and airplay. However it was also a hit on the US R&B charts through airplay. The album was certified platinum by Billboard in June 2004 and was certified double platinum in late January 2005.
Part of the album’s chart success is due to concertgoers receiving a copy of Musicology, with the album cost included in the ticket price for the Musicology Tour. This prompted Billboard magazine and Nielsen SoundScan to change its chart data methodology: For future album releases, Billboard says that customers “must be given an option to either add the CD to the ticket purchase or forgo the CD for a reduced ticket-only price.”
