"Single Ladies"

OMG!! I must really be a nerd! While I was watching "Glee" last night (I love this new TV series), I really got caught up in this song by Beyonce. I like the rhythm and the words to "Single Ladies", and the actors did a great job dancing to and interpreting the music. I'm sure this song has been out for ages now and I'm just getting around to hearing and liking it. I'm stuck somewhere in the "oldies" generation and I need to get out.
