Well theres a thread similair to this...but I decided to make one to show off eachothers music we have discovered in games!
Anyways I'll start with mine
Dark Cloud series! It had amzing music that stuck in your head for hours and hours....I'll never forget those first tunes!
Dark Cloud 2
Dark Cloud 1
My second opinion would have to be Dragon Quest 8...yeah it sometimes gave me a headache but overall the music was solid!
Check it out
Last but not least Shadow of the Colossus did a great job as well
Here it is
If your wondering how to present your music just go to google.com and type in your game's name and put music after that....simple...but just a heads up for the clueless
