Rihanna is definitely one of my favorite artists of all-time and my second highest played artist on Last.fm. Although, unpopular opinion, Anti was terrible.
#47 - Rihanna - Disturbia
Rihanna has had nine songs in my countdowns. Her highest was #2 in 2013 with "What Now". Originally this song was unranked because I hadnt started doing countdowns yet.
Disturbia < 333
