If you would like to be tagged, say so in the comments. I'll be tagging the 30 highest color levels to ask. If you haven't commented on any of them again after 5 or so, I'll remove you from the list.
#49 - Break Free - Ariana Grande ft. Zedd
Fun Fact: There are a few coupled artists to start the countdown off. Ariana was in both #50 and #49. There will be a repeat coming up shortly and then few after that.
Hint for #48: It came off of an album that briefly passed Beyonce on the charts when she released her album.
