It's interesting how I get a thrill when a song I love comes on the radio. Nick Lowe's "Cruel to Be Kind" or Dave Edmunds' "I Hear You Knockin'" are two good examples. It doesn't matter that I have the song in my CD collection and I can pretty much listen to it whenever I want. Somehow it's a special thrill and I have to hear it all the way through. I think it's somehow about my taste being validated.
