another good post, thanks for your efforts!
FWIW copywrite to post sound clips is generally 30 seconds or less (fair use). it's not a written rule but no one has ever been slapped over it. i believe you have violated site rules by posting that link, however, so you might want to remove that ;)
Thank you for the comment - and I will remove the link. I merely wanted to show what is not permissible - one can not pretend to post an entire album while pretending it to be "for educatinal purposes/fair use". I am the first to condemn such behaviour - as I would not like anybody to "educationally" distribute my own work either.
