Why is there an album 7-3, and 7-5 but no 7-4? is there a missing album out there?
He actually skipped over 7-4. He originally wanted to release 7-3 and 7-4 together (3+4=7), but ended up only releasing 7-3. 7-4 seemed like a bad omen to him (four and death are closely related to each other) so he just went on to 7-5.
What do you think?
