Basic premise is that you use the song from the previous post and name another song with at least one word from that previous post.
Post 1: Singing in the Rain
Post 2: Blame it on the Rain
Rain being the word carried over.
Post 3 must name a song with any of the words from blame it on the rain, e.g. blame it on the boogie.
So first song.
R.E.M. - It's The End of the World As We Know It (And I Feel Fine)
