Should customers strip the drm from their downloaded music? You did buy it. Why should apple get to know which computers I want to listen to it from. Infact, why should they get to know how many computers I even have! "DVD Jon" has a good tool for stripping the apple drm. To find it search google for "DVD Jon" or "Justetune."
I don't know if it is wrong or not, my concern is that someday I will forget my password to my Apple Store account and need to spend days to get it reset (which is probably tied to an email address I know longer have). In addition, I have more computers in my home (that I own) then Apple is willing to allow me to use to listen to the music I buy. What a crock!
