I wanted to know if anyone was experiencing the same thing I am.

Whenever I use coverflow, which isn't often because I don't like looking by artist.. I notice ram goes down continually until it hits the bare minimum and when I exit coverflow I still have about 8mb available. Freeing memory does not fix the problem.. I still have way less than what I should have with no apps open. But respringing frees up all of my ram. Is there any reason or fix for this besides respringing?
