Only if they use DRM. It’s not possible for me to lose access to the music I’ve purchased on iTunes, the games I’ve purchased on GoG, or the audiobooks I’ve purchased on libro.fm. (Except through my own fault, which shouldn’t apply.)
iTunes doesn't use DRM anymore? I haven't used it since I had a 1st gen ipod mini back in high school, but I remember only certain music was available without DRM and you used to have to pay extra for it.
When they dropped DRM, they raised the price a bit. I don’t remember them ever offering a choice, but I could be wrong—regardless, the slightly-more-expensive, DRM-Free songs are all that’s available today.
If you purchased music before the switch, that does still have DRM. (As an aside, you can get rid of it by setting up a VM with an old version of iTunes and Requiem.)
