Anyway what's your favourite radio station on TF2?

None of them.
There is no "TF2 Radio."

!radio plays stations from SHOUTcast radio, usually based on server preferences or set-up of the !radio plugin.

SHOUTcast is it's own site with it's own radio streams unrelated to TF2.

Usually a server admin will add a plugin to their server to quickly link users to the SHOUTcast stream of their choice (selected from whichever stations the plugin is set up to have).
