Sign up for a music subscription service such as Spotify or Apple Music (there are others and you don't need an Apple computer to use Apple Music).
These services cost around $10/mo on average. Not only do you have streaming and download access to pretty much every album out there, but you can upload your own music and it will be stored for you to retrieve at anytime if needed (or you can just stream it).
This comes in handy for me because for many years from about the 1970s to 1990s, I taped an enormous amount of content off the radio. Top 40 shows, Christmas shows, live recordings, and other things not available to purchase. So I have quite the investment in music myself, as it took me many hours to convert it all to MP3 format. With a music service, I have piece of mind that all of it is backed up.
Even if you decide to cancel the music service later, you can still download your uploaded content before doing so (however, anything you downloaded that was not yours, you will lose).
$10/mo might seem expensive to some but for me it actually saved me a lot of money as I used to buy at least 3-5 music albums a month prior to going with a music subscription service. Now I don't buy any albums at all, while having access to all of them.
For a music fan, it's a real good deal.
Some of us prefer to have hardcopy backups of our data. If you don't own it, you can be denied access to it at any time for any reason.
