Yeah, I feel like there needs to be a solution to this. Thankfully, artists don't generally have hugely enormous catalogs that would take up terabytes of space (my entire collection is less than 400GB, which is many, many times larger than any single recording artists catalog, even the Beatles).

One rub I have with limited downloads is that memory of broken CDs. I bought a mobile app that is about $200 and they limit the number of times you can request are-download before you have to buy another license and I think it's messed up. I've had to store that APK on multiple flash drives, off-site, etc.
