I had a dual CD pressing of Bach (double violin concertos plus some other stuff, Zuckerman/Perlman, Colombia passed through a number of subsequent buyouts and re-releases) which simply would not index correctly from the cd-id track stuff.

I wound up making an account, uploading the info, managing the 29 different reasons a neophyte makes a mistake causing their data not to be accepted, and finally got my CD into the system. This included using a random chinese persons web from the 90s who presumably had come to Australia and bought the identical pressing which appears to be a hyper-local market specific variant of the ones which other (European, American) markets got.

I have massive sympathy for the brainz, because as this article on ISBN and my experience shows, people are cavalier about renewing their 'unique identity' info, when they think they don't have to.
