Don't know whether it's been brought up before but you can hear many of the XM Radio stations from AOL. Just Google AOL XM Radio and download the software. The 60s station is great. Here is the stream which can be entered into IE direct: uvox://firehose-bbnm.stream.aol.com/stream/22219?authToken=r%3D6589521%26sid Great music and jingles.
Another station is Radio Bop http://www.radiobop.com/ which plays non-stop oldies with those PAMS jingles.

Enjoy
