Actually it is "I'm in love with that song".

Alex Chilton as it was already said fronted the 70s Power-Pop band Big Star and the Box Tops who had the 1960s hit "The Letter". I have heard Westerberg say on occasion that he just threw Chilton into the song but Peter Jesperson the manager/twin tone guy said that he took Westerberg along once to meet with Alex Chilton and Westerberg wrote it after that experience.

I think this song is pretty universal. It really gets at how it feels to really just have a band hit a chord with you.

Big Star are pretty wicked. I am a big fan of "I'm in Love With a Girl" and "Thirteen" in particular.
