Catholic music station online?

I'm not sure where to post this question, so I'll just put it here.
I'm looking for a site/radio station (whatever), that plays Catholic artists.
I can find Catholic talk radio stations, and stations where every Catholic artist I click on wants me to purchase their music, but I just want to listen for a while to see who's music I really like. I don't want to listen to just little clips, but really listen to full songs, from a wide variety of artists.
In my exploration, I've downloaded Real Player, iTunes (in addition to my Windows Media player), and the talk stations mostly work, but I am just stuck on getting full music stations - maybe because the ones I'm going to only have the option to purchase it??
Please feel free to contact me directly in addition to posting here (as I've run into a lot of trouble getting messages that say someone from cathswap is trying to contact me, but not being able to connect to the message here.)
