Based on the error, it would look like you have not created and populated the 'users' table in the database, because ""music_library_development.users' doesn't exist".  Did you create a migration file to create the 'users' table?  Did you run it ('rake db:migrate')?  Did you run it against the right database (production vs. development; I would guess you are currently running against the development database)?  Or if you manually created the database table, again did you do it for the correct database --- production vs. development?
