Your kids have iPods, you have an iPhone and your husband or wife has one too? You like Jazz and your kids like Rock? You need to manage all these devices and tastes on the only computer of the household? iLibs is the only comfortable and safe way to create, manage and edit several iTunes libraries on a single computer and switch between them without ending up with music you don't want on your iPod or losing precious songs by mistake. Ever tried to manage several iPods, iPod Touch or iPhone from a unique PC? After a couple of unwanted synchronizations of your iPod songs with the ones from other people's libraries, you probably ended up creating several Windows user accounts to keep your music and the one of your friends or family separated, which is long, complicated, unsafe and inconvenient. With iLibs, you easily create and control more than one iTunes library, while logged in the same Windows account, on the same computer. Create different users and new libraries for each of them, either from scratch or from your existing libraries or the ones of another user.
