I just found out that Lancaster Baptist Church, where our boys are in college, has an online radio station. Great music, 24 hours a day! Here's where you can listen: Lancaster Baptist Internet Radio. There are several listening options available; I'm sure you'll find one that fits your preferences.
A few other good internet radio stations:
Old Christian Radio - all music
Fundamental Broadcasting Network - all music
Gospel 90.3 - Landmark Baptist Church, Haines City, FL - live radio
WTBI Radio - Tabernacle Baptist Church, Greenville, SC - live radio
I'd love to know of your favorite internet listening; leave a comment!
