Beginning July 1, XM will present the "IT" special on the Decades channels. It starts on Channel 4 (The Forties), then moves on decade by decade through the 90's. Supposedly, every hit song is played, but that would be difficult to verify. I do know that they play literally thousands of songs, beginning with the 1930's and 1940's and ending with the 1990's. Details can be found at the following link: IT - Pop music special. Get ready for a long journey down memory lane. Enjoy! Steve K.
