School radio

The school has all the gear to run a radio station, and has for a number of years. However, due to things that have happened over the past year it hasn't been running. I found out that the computer running part of it was donated a number of years ago and is pretty much dead. I have managed to get another one up and running.

We have all the nz on air cd's and are looking at converting them to digital.
Windows media player or iTunes? To create play lists or is there possibly something else?

Is there an open source radio station agent?

But it also gives me something to do with my students, creating material for the station.
