I just love this:

Schoolhouse Rock - "Playlists and discussion topics from a weekly radio show on WSCB 89.9 FM, Springfield College, Springfield, MA, hosted by reference librarians Emily Alling and James Miller." (no feed)

Sadly, the radio station doesn't stream, but check out the playlist from their first week:

Sam Cooke, Having a Party
Belle & Sebastian, Wrapped Up In Books
Rolling Stones, You Can't Always Get What You Want
Smiths, Bigmouth Strikes Again
Led Zeppelin, The Girl I Love, She Got Long Black Wavy Hair
Internet Gem of the Week: Howard Dean, Remixed (http://deangoesnuts.com)
Ben Folds, The Luckiest
Modern Lovers, Girlfriend
Lauryn Hill, Can't Take My Eyes Off You

Plus, discussion of Boolean logic.

Anyone who can blend Belle and Sebastian, Ben Folds and logical operators scores big points in my book.
