I would be remiss if I didn't suggest listening to the station of my alma mater, WSAJ 91.1 Grove City... you should be able to lock it north of the PA-528/Evans City exit on I-79 (definitely by exit 99). Classical by day, BBC news, jazz at night, and some fun weekend programming.
The Youngstown stations are pretty much standard fare compared to other similar sized markets - two big owners in Clear Channel and Cumulus covering the popular formats. WKBN 570 has local news/talk during much of the day.
Sometimes it is also fun to see how many "Froggy" country stations you can get in one given location. Around Grove City with a good tuner, you can get 95.1 (the local Froggy), 95.5 Johnstown, 98.5 Oil City, 100.3 Meadville, 103.5 Burgettstown, and 104.3 Moon Twp...
