Normally either dreamy dungeon synth or black metal
I like Sequestered Keep and Fief, I often out on ULK or Fogweaver if I'm trying to drift off to sleep. Quest master is good too. Atlantean Sword is another I've listened to a bit recently. Best album for me is either Fief II by Fief or Depressive Silence II from 1996.
I've also released a few DS albums/experiments. They are on my page. Check them. Cheers
