I rarely check my inbox here so if you send me a message it might take me a while to get back to you. If you guys really need to talk to me go to my website and click the contact link.
However, to answer (most) of your questions:
Yes, you can use my music for your video game, youtube movie, school project etc. as long as it is non-commercial (i.e. you aren't making money off of it) and you give me credit. I would appreciate it if you could link me to your project when you are done as I like seeing what you guys create.
No, I do not have a tab for Please Intro or BFG23! I don't tab out my own songs!! If you search on the internet there are some tabs, but for the most part these are about 50% right. If you want to get better at guitar and music in general, I suggest you learn to play songs these songs by ear. They are both played on guitars tuned in Drop D (DADGBE) and make use of open strings in order to be playable and sound right.
I love all you newgrounds people and I am sorry that I rarely post new music anymore (unless it is a parody song or remix it seems). I assure you that I am writing new music still but most of it has either been for commercial projects or would not be suitable for newgrounds (re: avant-garde classical).
There is a new project that I am working on at the moment that I am dying to show you all, so I will post it here when it is finished.
