Old iPod - Cannot See Music in iTunes Music File Explorer

My husband has an old ipod touch that is on a deactivated ID. It is splitting. I wanted to move the music from the ipod to itunes. Here are my recent steps. The computer I'm working on is less than a year old. I recently downloaded iTunes and using a 3rd party app downloaded my music from another another different ipod to iTunes off a newly created apple id. My other ID was deactivated over the past year and apple won't reactive it. On my husband's ipod I see the music in iTunes itself, when plugged into the computer, on an old deactivated id. He doesn't remember the password to get into the ipod and doesn't use the email it's showing on the device. I don't see the music in the file Explorer. I see pictures. I see the DCIM folder. No music. No ipod_controller either. I went into devices and system folders and updated the drivers. No luck. I want to move the music from the ipod to the iTunes.
