That's true, but they clearly state that it's an alternate timeline in the film itself.

Besides, it's not like Abrams came by your house and took all your Star Trek DVDs and destroyed them. You can still watch them just as easily as you could before the new film came out. Nothing's destroyed.

And I happened to enjoy the music in the film quite a bit, especially the main theme. And I was quite happy that the Alexander Courage TV theme was used at the end, though my personal favorite is the Goldsmith Motion Picture theme ... how disappointed I am that it's now the "Next Generation" theme ... ugh ...
