You sure about that? I have a friend who thought that too but found out 7 years later that only a bankruptcy will disappear after 7 years, not just idle delinquint accounts. He needed to actually file for bankrupcy to make it go away. This was in Usa, NY; maybe it’s different other places.
As a second “data” point: I have some accounts on my credit report that have not been touched in a decade+ yet they are still there (they are not delinquent).
I thought that most artists never made much from record sales, it was always live performances. The label gets record sales.
