Drake tops iTunes' year-end music lists

Rihanna, who collaborated with Drake on her smash "Work," held the No. 2 spot on the top album's list with "Anti," while Adele's "25," Frank Ocean's "Blonde," which also debuted on Apple, and Justin Bieber's "Purpose" rounded out the top five.

In an interview, Eddy Cue, senior vice president of Internet Software and Services at Apple, said that 60 percent of those using Apple Music had not purchased any music from iTunes, and noted the growth in its exclusives with artist, from Frank Ocean to Chance the Rapper.

Cue said one of the biggest lessons learned is Apple Music was making it easier for consumers to use, from access to its playlists to its radio stations on Beats 1.
