This is a sweet little app. No matter what I am doing on the computer I always have music playing in iTunes. Now, I can control it without opening every time I want to change songs, adjust volume, etc. If I never open iTunes, operating via keyboard shortcuts, as opposed to opening 50 times a day; I can only imagine how much time this saves me over the course of a year. It is worth 10 bucks. It is a bit high in memory usage, which is my only complaint.
