Second reply, holy shit I'm furious about this. I seriously will not be surprised in the least if they DO rip me off. I honestly did apply to that company (it's based about an hour from where I live) and honestly did send them several of my opeth tabs, all of which they absorbed, and then sent me some bullshit test where I had to transcribe some pearl jam song, which I did, and after not hearing from them for a month or two I inquired, upon which they said "oh you didn't pass our transcription test, buy some more of our tabbooks to improve your transcription skills."
Of course, they'll probably sue ME for putting my tabs on the internet if this comes out, even if they've been there for years before this book comes out and even if they directly rip them for their fucking book. This makes me never want to transcribe again, seriously.
