When I try to downlod music, I receive an error ... " this device can not be transferred. This device must be linked to your apple ID to ply content saved offline. This device is already linked and cannot be transferred for 20 days."

Hi Cris82c,

Thanks for coming to Apple Support Communities for help today with playing music. It sounds like your devices was previously associated with another Apple ID.

Have a look at this page: See and remove your devices that are associated with Apple ID purchases

"When you try to associate a device that was previously associated, you might see a message that says, "This device is associated with another Apple ID. You cannot associate this device with another Apple ID for [number] days." You might need to wait up to 90 days to associate the device with a different Apple ID."

Have a fantastic day!

Cris82c,

Did your boyfriend follow: What to do before you sell, give away, or trade in your iPhone, iPad, or iPod touch? If so, there wouldn't be a waiting period.

Cheers,
