I'm not a fan of iTunes, so I won't install it on my MacBook Pro. It's a memory hog and I don't like it messing with my music files (organizing, etc.), so I was looking for a free mp3 player to install and found a nice little app called Audion. It used to cost money, but they stopped supporting it, and now will give you the serial number for an unlimited use install.
