I do not own an MP3 player but I'm interested in getting one. There are somethings I'm not familiar with. I always picture an MP3 player as being like a walkman where you just listen using headphones. Can an MP3 player be plugged into my home-theater system so I can listen on my surround sounds? Can it be plugged into my car stereo somehow, and if so how does the MP3 player connect to it?

Also, what features should I look for in an MP3 player? I know I want one that has quite a lot of storage capacity.
