Aries,
When I called Aderet, they told me that most artists do allow one copy for your own use. Most lease agreements only prohibit anything which facilitates copying for others. Only some specific artists do not allow even a copy for oneself. i don’t think you have to assume it’s a problem unless it specifically states it (but of course ask your rov).
Most of this discussion, in which I opined that even copying for yourself would be proscribed by the rental agreement, is only relevant in those exceptional cases.
I wouldn’t blame Aderet, it’s up to the individual artist, Aderet is just going along with their wishes.
I will repeat that I am not at all involved in the music industry (except as a consumer), but I would hate for my comments to infringe on anyone’s enjoyment or cause a loss to Aderet.
