While I don't dig Green Day, I miss the days when you could turn to a place on the dial and couldn't tell for sure what was going to be played.
Maybe I am unusual, since all the genii that are programming FM nowadays have determined that they will only give listeners what surveys say they want to hear. But I cherish my memories of pre-Walkman Top 40 radio. After being only allowed in my single-digits to listen to the "beautiful music" stations (department-store instrumentals of hit songs, Roger Whittaker, Andy Williams, Perry Como, etc) and 60's "MOR" or Middle Of the Road stations (Herb Alpert, Tom Jones, The Lettermen, Carpenters, etc.), KFRC (San Francisco) was a revelation to me. Hard rock, country, R&B, disco! When I got out of school, I ran home to turn on the radio up high before my sisters and parents got home.
KFRC exposed me to other forms of music that I never appreciated. The closest thing to that experience nowadays is Launch, an online radio station that lets you program your own channel. Today, due to the current radio trend of "narrowcasting" instead of "broadcasting," it's tough to explain why I don't hate Led Zeppelin even though I like Missing Persons, or how I can groove to the Police, Lynyrd Skynyrd, George Benson, The Mamas and the Papas, Rush, Bootsy Collins, The Ramones, Traffic, No Doubt, Chuck Berry, Abba, Def Leppard, Adam Ant, Toby Keith, Motorhead, James Brown, and yes, even Roger Whittaker back-to-back.
