Tim Beek is the sound engineer for the project Om Mani Padme Hum. He has made more then enough music to share it with you! He has music in several genres and categories (with a lot of focus on games). Over time more and more numbers will appear on the website.
You can download his music for free and use it (for free as well) in your commercial or non-commercial projects as long as you attribute his work. This means putting his name (and website!) in the intro or opening screen or heck even in the credits as long as you attribute the used music to him. You can reed the license here.
Also he can make custom music for your project (however not for free). If you like that idea, either way contact him trough the contact page on his website or give me a PM that I will address to him.
