I also want to add that you can use an extension that automatically submits pages that you go to on your computer to The Wayback Machine so that, even if it is deleted, you can easily find the artist and song by searching on Wayback Machine. The easiest way to archive it for someone who doesn't have a lot of technical knowledge is to turn the extension on, mute your computer, and then let your entire playlist run on 2x speed (or whatever the fastest is) while you sleep.
Is this the easiest way of backing things up? No. Is it possibly more convenient to download the media for your own collection? Yeah, but if your technical knowledge is limited or if you don't currently have access to a lot of storage space, this could probably be of use.
