If you need any proof of how Twitter has affected our culture – just look at what’s happened to the old number sign. Back in the day, "#" just was a way to denote the word “number.” But throughout the past past few years, that humble little symbol has taken on a new title -- the “hashtag” -- and new significance on Twitter and other social media. And, now, it appears to have officially infiltrated the music biz, with hashtagged song and even album titles popping up all over the place. In the past month, artists like will.i.am, Mariah Carey and Busta Rhymes have all released songs with the symbol in the title. 

Joining us to discuss are Lexi Mainland, social media editor for The New York Times, Rembert Browne, staff writer for Grantland, and William Gruger, social/streaming chart manager at Billboard.
