You can get the soundtrack at most sites that sell Japanese music...I got my FFVII and FFVIII OST imports from YesAsia.com, pretty good and reliable, but yeah, it's expensive. That's all because of expensive CD prices in Japan though, singles alone cost like 1200 yen...which is like, $11.
SquareSound.com's online store also has it, I believe.
Then again, there's always bootlegs on eBay for like...$5.
Don't feel awkward, like I said, it's totally understandable. Of course, I avoid the guilt trip (which I get with anything on my computer just about) by keeping only PSFs of OSTs I don't have, so I can argue "well, it was all in my game, and I bought that!" Lol.
If you're mic keeps malfunctioning, you can get a decent one at places like Staples for only around $10.
As for the mine name thing, it sounds unnatural anyway, inaccuracy aside. I mean, it sounds like "my name" anyway. Just with a stress on the 'n'...
