If you are the proud owner of any portable media player other than an Apple device but have your entire library locked neatly inside the iron walls of iTunes it is highly likely that you have experienced a certain level of frustration by your lack of sync-ability with this device.

One could make an argument that iTunes is not the best mechanism to manage a media library, but that's not really a point worth discussing. There are others coming to market with products that have iTunes as their aim: Amazon Cloud Player, Google Music, DoubleTwist, etc. - but let's be honest with ourselves. iTunes isn't really broken, and most of the new content providers are spending time and effort to integrate their products into the iTunes experience. Why are they doing this? The answer is simple, market share. iTunes is quite literally everywhere from the drug store checkout line to the set top box. The platform isn't going away any time soon - so my decision is to play nice with it.

Now here we are with the problem: There are good devices on the market that do not carry the Apple blessing so they simply don't work with iTunes - or at least not well. I have tried all of them from totally cloud to conventional sync tools and have not been impressed.

My goals with this project are simple:

• Establish a simple, lightweight interface to sync my iTunes library to any USB connected device.
• It must work quickly.
• Sync must be true two two way transfer. 
• A song purchased on the handset from Amazon should show up in iTunes when I sync it. 
• Deletions should propagate to all devices regardless of where they are deleted.
• Playlists should move from iTunes to my device.
• There must be a way to limit which portions of my library sync to the device.
