I truly feel sorry for everyone affected but it’s also important to draw firm conclusions from this happening to oneself.

I’ve had this happen to me once, bought myself an Album on Amazon Music, back then the Amazon Music App was rather unusable so I just downloaded the MP3, years later I wanted to redownload some of the “worse” songs from this album I had deleted/lost over the years. Gone, the entire thing gone. Still there in my purchase history, unavailable anywhere else. Best part: the album itself was still on Amazon so I could have bought it again.

I drew my conclusion: Never buy with DRM. Always download the files, even if I don’t need them.
