Feedback - Act 6 No Boss Music

I've just killed the first three bosses in Act 6 and noticed that for all of them the music didn't change when entering the boss's area - it continued playing the atmospheric music from the previous zone.

I'm not sure if this was intentional or not, but I found it left the boss fights feeling incredibly underwhelming (I walked into the middle of the zone and saw the boss and sat there thinking "oh, look at that, it's a boss..."), as opposed to when you first enter say the Warden's room in Act 1 or Vaal Oversoul in Act II and you know you're about to have a huge fight simply from the music that starts playing even before you see anything.

I haven't completed Act 6 or any higher yet so I don't know if the rest of the fights are the same or not but if you had generic\reusable boss music I would definitely add it to those fights to improve the immersion.

Cheers!
