Awesome. If you find yourself really liking a certain track, don't be afraid to ask for a donation/payment for it . You'll find that there are a lot of people here willing to support artistic creators.
On that note, if I find a track from you that I like and need one for a project, even if you're not asking for payment, I'll likely send you one anyway. It won't make you rich, but it'll be better than giving it away for free!
