Neil, from a legal point of view (and of course I could be wrong) it is my opinion that you are absolutely correct. In additon to selling the copyrighted sheet music (because isn't that what tab are?) there is the issue of hosting the songs on a site that makes money selling advertising, Thus you are making money "giving away" my sheet music.

As for nanikure, yes I play an instrument and I have bought music books but only artist specific. You are correct about the "cheat books" that's why I would not buy them.
i-tunes has solved the album problem by allowing you to buy one song off an album (except the apple catalogue but that is their loss-the apple vs. apple lawsuit is another issue. I read the agreement and was not surprised that Apple Computer won)
I suggest that you leave out the "rich bastards", and "got too much money already" arguments out because they just make you look stupid. There is a great scene in the movie "Network" where Ned Beaty brings Peter Finch into the boardroom for a little chat. He says something like "You are fucking with primal forces of nature. Do you think they sit around the Kremlin discussing Marx? No, they talk about the price of wheat" You see, in the real word where grownups live, nothing happens until one guy sells something to another guy. You want free stuff, move back in with your parents.

Dohrt, you have the wrong impression. There is nothing wrong with playing a song. There is nothing wrong with transcribing a song. Kids that play in talent shows are not breaking the law. Bars pay a fee to ASCAP and or BMI who then pay royalties to the artists. If I have a bar I will usually have music playing to entertain my customers, I am making money partly from the music so I have to pay for it. Radio stations pay the fees based upon their Arbitron rating which also sets the rates for advertising on the station.
Now, as for your "classical song" I would assume that if it is "classical" then the copyright has run out and it is in the public domain. Your recording is subject to copyright protection, thus someone cannot use that in a commercial venture without compensating you.

Without getting too much into it, there is a thing called "compulsive license" that allows my band to do a cover of your "published" song without your permission but I have to pay the fee. Using the song in a movie or a commercial or the like is different and requires permission and a negotiated fee.
