A childhood belief about songs

I wasn't into rock music until this year. In may I heard a song by The Who for the first time I thought was called Teenage Wasteland. Over the summer and fall I kept hearing reference to a song by The Who called Baba O'Riley that was supposed to be one of their most iconic songs. I could never understand why I never heard it on the radio, and wasn't quite curious enough to look it up online. Yesterday I looked at the recently played list on my local radio station's website to find out what another song I heard was, and I saw that Baba O'Riley had played while I was listening. My jaw dropped for an entire minute when I realized that "Teenage Wasteland" was really Baba O'Riley!
