While I'm eating and holding out in case the server goes down again... I just bought the new Tron movie soundtrack by Daft Punk and its a good STO soundtrack IMO...
What else you guys listen to?
Daft Punk's score for Tron: Legacy is indeed rocking.
For me, almost anything by Two Steps From Hell, or X-Ray Dog's trailer music will make for a fine Trek episode. The VGRemixes by Bart Klepka and Jared Hudson. Almost anything by Rob Dougan and Clint Mansell. But head and shoulders above all that, "Requiem for the Ring" -- the music that Mansell did for "Requiem for a Dream" remixed for the Two Towers trailer -- is so full of awesome, it was the real cause of the Hobus supernova.
