This is why the happy medium is owning your own data.

You can have the CDs or not, but owning your copy of the MP3 file, which you keep on a hard drive, or on a thumb drive, or on a portable SSD (in any of these cases, with a backup somewhere!), or wherever, means that

1) you can play it any time you want, for no extra money

2) your access to it can never be revoked

3) you can keep copying it onto new physical media any time you're worried about the old one wearing out
