Looks like you're trying to insert a UNIQUE value in your database that
already exists. do a "SELECT count(myclass) FROM mymp3 WHERE myclass =
'class_four'". If that returns 1, the value already exists. This is caused
by the record variable set to PRIMARY KEY or UNIQUE, which prevents you
from having two of the same values :)
