Hi i was wondering does anyone know how to put thier own custom music into the single player game???

You need to check the forums for related posts before you make a new thread. Someone else asked this and I helped them out. Check the thread here:

You can also take some MP3's, name them after the audio tracks in JA, pack them up into a pk3 file (use zip and just rename to pk3 extension) and put it in your base folder!

You can also try muting the music and just auto play a cd or mp3 track of your choice (it helps to have a second disc drive if you're going to play a cd though).

Otherwise the link provided is a great start.
