Did you make this site? If I were the creator, I would not show it to strangers until I seeded it personally with 100 or so tracks. Nobody likes an empty party.

Thanks for having a look :) If you're an an ameter orchestra, or even most professional orchestras then all of your money is made from people coming to your concerts. Thus - if you had a way of getting free publicity by getting your name out there (and sharing the music you and your fans are passionate about) you'd be irrational not to.
