I like listening to the soundtrack from the game most of the time. Non-star wars music for something Star Wars related just doesn't work for me...even in star wars role-plays outside the game.
HOWEVER.
I have a few songs that remind me of the Mandalorians. So if i'm on a mood for it, I have three songs on repeat.
'Sons of Plunder' - Disturbed
'I stand alone' - Godsmack
'Welcome to the family' - Avenged Sevenfold
