I'm always on the lookout for web sites that play oldies music. I can listen to them in the background.
My brother-in-law Paul sent me this one -- the Playa Cofi Jukebox at http://www.tropicalglen.com/.
This has Top 100 songs for the years from 1956 to 1982. However, the web site selects 10 songs from each year and plays them in the order they pick - not the order you want. You can always go back and pick another year and pick one you like.
Another site is at the Briarcliff Manor High School Reunion site at http://www.bobforrest.com/JukeBox.htm. This site has only 1956 to 1960 songs, but those are the best anyway!
Got more suggestions? Tell me!
