Any of the Star Wars audio novels (movie adaptions) from what I recall, all had sound effects and music.
I have not listened to my LoTR / silmarillion in a long time (pre-Jackson), so I don’t recall how many voice actors were in it, but it was the BBC radio drama.
Batman: The Complete Knightfall Saga has a whole cast of voice actors plus original music composed for it.
Superman Lives! also has a whole cast of voice actors plus original music composed for it.
My DragonLance: Chronicles are all by one narrator, but his does a great job of making each character sound different.
Same goes for Conan audio books (The Coming of…, the Conquering Sword of…, the Bloody Crown of…), as well as Savage Tales of Solomon Kane.
Each time I look for more MP3-CDs, all I get are those darn download sh!t.
I want the physical media.
