Hi Simao,
I'll be interested to hear what you decide. I have about 800 mostly classical and jazz CDs that I've ripped to both a Sony HAP-S1 and to an external hard drive for backup. I haven't played a CD (except for some comparison purposes) in many years and, given the convenience of the Sony, don't see myself using them. Right now, the CDs just sit on shelves as part of the "decor" in my living room. I should donate them to a charity such as the public library or maybe Goodwill. But being pennywise and pound foolish, I need to inventory them in order to take a tax deduction, which I've been too lazy to do. If a calamity occurred and the Sony, the hard drive, and the CDs were destroyed, I'm lucky enough to be able to switch to streaming services.
To answer your question more succinctly (and rhetorically), why not just take them to your public library, which will make them available to people who will enjoy them?
