Why is it that some of my songs are low in volume? I have alot of varying quality on my downloads from LimeWire. When I use my vehicle cradle, i use the lowest FM channel, but I have to max out my volume just to hear the songs. The volume/quality is OK when I use my earbuds, but I still can hear background hiss. I have no idea if I am downloading the wrong way or if there is some setting that I have not set/set wrong. Does anyone have the same problem or have an answer.
