I will state a caveat: these are MY top albums. I picked each one because of the value I have placed on them - in my memories and in sheer volume of listening hours. Also, I didn't want to narrow it to a specific number nor did I want to rank them - my rules.
So while I ponder how to spend the +$200 that Lala is giving me to spend in iTunes (because of the amount of money I spent on web albums) - enjoy!
