I will use it under one condition: that my edited tags are included. I spend time making sure music added to my library has the correct date, etc. I hate buying an artists collection from a decade gone by with the date on all the songs being the original CD release of last year for instance. I also add group identifiers and/or comments for smart lists. Holiday music may be jazz but be in the "Yule" group.
I'll hate it if I download to another device from icloud and find that all my work is replaced.
