WTF at #4? Never even heard that song in my life. If you're going with ABBA, why not "Dancing Queen," "Mamma Mia" or "Fernando?"
Other than that, I like all these but I didn't vote for "Crazy In Love" because it wasn't really that iconic ("Irreplaceable" and SL had a bigger impact on pop culture) or "I Want to Hold Your Hand" because it was a throwaway hit for The Beatles.
