VH1 has announced their 2011 Song of the Summer and after another great summer full of amazing songs, they have chosen the popular party anthem “Last Friday Night (T.G.I.F.)” by Katy Perry as the winner.

The people at VH1 originally thought that talented songstress Adele would take the crown with her hit “Rolling in the Deep,” but after Katy Perry’s ode to forgotten Friday nights was released, it soon dominated VH1′s Top 20 Countdown.

Other summer hits that made the 20 song list included “Party Rock Anthem” by LMFAO, “I Wanna Go” by Britney Spears, and “Pumped Up Kicks” by Foster the People.

You can watch Katy’s acceptance speech and see which other awesome summer songs made VH1′s list here.
