Do you have multiple song libraries with iTunes on multiple computers like I do? Do you hate having to trying and synchronize the libraries by using external hard drives, flash drives, CDs, and other methods? Luckily for all of you that find yourself in the same situation as me, there is an application called syncOtunes that will synchronize multiple iTunes libraries together. Available now in both Windows and Mac versions, and the best part is that it's freeware!
The only thing that's not totally clear is whether you can sync together a library on a Windows machine with a library on a Mac machine, but since that's the situation I'm in, I'll be trying it tonight.
