they pass everyone and accept everyone. i can change the styles accordingly but it is somehow annoying. imagine emotions represented by an elephant (yes, you read it right). each track is so warm and inviting when you hear them for the first time you feel like they are already a part of you. some of the type b rotors have a date stamped on them (digits for the month and year). thank you so much for your help and for finding innovative ways to explain bs.
