I bought it at Gen Con and used it a week later in an adventure.
Overall, the tracks are good quality--not John Williams, but nicely done. They all easily convey emotion and feeling.
For example, next time your players run into an Orc horde--use the "Beasts on the Borderlands" track. Think of what 100 orcs or dwarves sound like marching, clanging their shields in unison and that describes the track (set to a deep bass background music of course)
My favorite track is "Deep Trouble" which I used for a combat sequence. It has a very anxious, tense combat sound and invokes an image of perilous combat.
I thought the weakest tracks were those that were repititious--of which there are a couple. However, even those (Relic Uncovered and Ancient Temple come to mind) have their place in any adventure.
Before purchasing the score, I recommend 1) previewing it on Midnight Syndicate's sight and 2) consider how you will use it in your game.
Music is tough to use properly while playing because it won't appeal to everyone's tastes but my players all commented that it added to the adventure.
I previewed each track ahead of time and wrote down my thoughts of the appropriate time to use each of them in the game.
You will want to put some of the tracks on repeat to use as background music.
Track 6: Stealth and Cunning was used in my game on repeat because the party was travelling in the Underdark, then I switched to Track 8: Skirmish, when combat occured.
I hope this helps and would be glad to entertain more questions.
