I read "Drums of Mordor" and the first thing I listen to is some electric instrument bull...
Now don't get me wrong, I'm a big fan of LotR and I know that the "Drums of Mordor" would sound like wardrums, telling you with the sound of their drums that they'l f*cking scoop your eyeballs, slit your throat, put your eyeballs in your throat and rip off your chest with their bare hands.
Hey don't get me wrong mate but stuff like this very seriously and you should think about it before you make something including a fandom with it. Mordor is a place of Uruk'hai, Orcs, Goblins, Beasts. If there's any of them playing a xylophon-like instrument making a song like this sounds like I'm sure he's not living for much long in Mordor.
You know which place this might be more fitting to? Elrond- Or at least somewhere like that. If you make "Drums of Mordor" make sure this song sounds like PURE EVILNESS and PURE HATE, ANGER and DESTRUCTION. Cos that's what Mordor means in the LotR Universe.
Now that I gave you a really long lesson in Nerdtology - to the track.
It isn't bad. It's really oldschool RPG-like, felt almost like WoW Classic on Alliance side or like Ultima I - XIII, the first Might and Magic and so on. It reminds me of the days where the internet was something you accidentally enabled on your phone and you panickly tried to disable it ASAP. Go on wih your work. It's like an oldschool pixely diamond that needs some grinding, some polishing. But don't you fricking dare to call a track like this "Drums of Mordor" ;D
