howdy @AutumnLegends , to have a different background for each main menu music would be doable .
I thought of another type of track, on the gpp BotsCamp mod when you first entered the server welcome music would play, along with a custom welcome overlayed animation/message (I think Cuboid had this as well).
I was thinking that the load screen might not require a music track, as for most people it is pretty fast, and for some it is almost instant. However, perhaps music at the download screen would be good to have, as sometimes that could take a couple of minutes even with a decent connection.
For the tracks you would like us to try, be sure to have them available in .wav format. Also, for use in Tremulous, it would be preferable to have the music licensed as cc-by or cc-by-sa (more information can be found here: https://creativecommons.org/licenses/ ).
I have a noobie sound cloud question…
How do I download a music file?
