Diablo 2 Soundtrack (Roger) 

Emotional piece of music

it's a modified version of the tristram theme part.. not exactly the same so that must be the reason to name it different :)

Meet Roger Our Deadliest Foe!

indeed it is. the melody sounds familiar..

You can always create a Playlist, which can contain the music from different acts.

this part is included in the tristram song of diablo 2

Part of Tristram music!

Could you mix up somthing like music from all the acts. Somthing like act1 allmusic, act2 all music and so on
