Totally agreed, I also love the sound of the 6th and the flat third in the Dorian scale, it has a "cool" sound to it that the regular minor pentatonic is lacking. I know not everyone likes video game music, but check out this song: http://18.104.22.168/files/jukebox/shock1/%5BGreg%20Lo%20Piccolo,%20Tim%20Ries%5D%20-%20Shock%201%20-%20The%20Reactor%20(Mac%20Mix).mp3 The distorted "guitar riff" at the end is one of the coolest riffs know, probably because it has a consecutive Dorian 6th and 3rd. Filter's awesome "Hey Man, Nice Shot" riff is Dorian, too, although it doesn't have a consecutive 3rd and 6th. Aw, crap, I was wrong. The song I posted doesn't have a tritone, it has the flat 7th and the 3rd played consecutively, so it's a regular fifth. Still sounds cool, though.
