I need a special Mp3 player for my computer
 

I am getting a computer for my radio station and we are going to daisy chain 3 hard drives so we can add a bunch of music files so whenever a DJ isn't on air, we have the computer playing Mp3's. I need a program, though, so I can list when the songs to come on and how often. Thanks to anyone who can help. Maybe there is a program for winamp, I don't know. I tried searching and I haven't found anything yet.
