This week we welcome “Young, Wild & Free” by Wiz Khalifa & Snoop Dogg ft. Bruno Mars to the list. Flo Rida’s “Good Feeling” was number one for a long time, until last week when Rihanna’s “We Found Love” finally knocked the song out. But RiRi better watch out, because Adele’s coming to “Set Fire To The Rain.”
