No interest at all why would I pay someone to listen to my own music and also limit my access to it. I think everything cloud is pretty much dumb with the exception of onlive and gmail.
I was going to subscribe for my Wife and my Kids but those Limits are holding me back after i had done a small research by taking a look at how many Songs my two Kids plus my Wife had inside their Folders and on their iDevice. Don`t get me wrong, it`s not that i will stop buying Music on the iTunes Store. That won´t happen ever since my daughter would pretty much kickass my butt but overall i lost pretty much my interest into iTunes Match that i had since it was presented the first Time.
