This happened to me tonight:
1) I got a craving to listen to Van Canto (German a capella metal band)
2) I looked up "A Storm to Come" by them
3) I got interested by the video and looked up the lyrics
4) The name "John Gynt" in the lyrics caught my eye, so I Googled it
5) I ended up on the Wikipedia page for "Peer Gynt", an 1876 Norwegian romantic dramatic poem turned play
6) Reading about the music in it, I recognized the title "In The Hall of the Mountain King"
7) I have now figured out where http://www.youtube.com/watch?v=dRpzxKsSEZg comes from
8) I looked up more stuff by Edvard Grieg and click on the "http://www.youtube.com/watch?v=dyM2AnA96yE"
9) I now know where the intro music to Peggle came from
10) My mind was blown
Has something like this happened to anyone else?
