WXRK

After New York City's WXRK flipped to Talk in 2005, the call letters were transferred to Cleveland, Ohio's WXTM which was co-owned by CBS Radio.  The new "92.3 K-Rock" flipped from Active Rock to Modern Rock and essentially mirrored the NYC "K-Rock" right down to the format, frequency and a very similar logo.  When 92.3 FM in New York flipped back to Alternative and re-took the WXRK call letters in 2007, the Cleveland "K-Rock" took the calls WKRI and a few months later changed them again to WKRK.  The Cleveland Heights, Ohio licensed station is currently a Sports station known as "92.3 The Fan."

Booker T Jones featuring Jay James - "Broken Heart"
Cassandra Wilson - "Lay Lady Lay"

Hilversum is the home of many radio and television outlets including international public broadcaster Radio Netherlands.  Some old radio sets even had a Hilversum setting on their dial.  (Click it bigger.)

I heard this song for the first time about a year ago.  Except for the ending which meanders a bit, I think it's just about a perfect pop song.  Why this wasn't a hit in America is beyond me although I imagine that DJs probably couldn't pronounce "Trijntje Oosterhuis."  I'm posting it here because it was performed live in a Radio 538 studio.
