Linux radio question

Just starting to listen to live radio using RealPlayer 10.0.2.608 w/ SuSE 9.2 (thanks to SuSE for the free 9.2 DVD ISO). Any recommendations for free Web sites and/or Linux tools for selecting stations and managing addresses for favorites? Have tried saving links to connections under "favorites" with RealPlayer, but I often get error messages indicating a possibly outdated or inaccurate link when I try to return to a saved station ... sometimes I can retrieve a live stream, sometimes not.
