Trying to put itunes on a non-apple device

Only the iPod/iPhone range and the iTunes enabled phones from Motorola are compatible with iTunes for Windows and with the standard copy protected songs from the iTunes Music Store. If your phone shows up in Windows Explorer and allows you to drag and drop music files then you should be able to add compatible files directly from your iTunes Music folder.

You can't convert standard iTunes copy protected songs, only the iTunes Plus purchases can be directly converted to another format. Where possible if you need to convert you should go for iTunes Plus tracks (iTunes songs are in AAC format). The only thing you can do with standard songs apart from playing them in iTunes or on an iPod/iPhone is burn them to Audio CD. You can use that CD just like any regular one.

You may be able to get your player working with iTunes with the aid of a third party helper program but you still won't be able to load copy protected songs. Have a look at this one and see what you think: iTunes Agent -Windows

The iTunes Store sells music in two formats, protected .aac, which will play only on authorized computers, iPods, iPhones and Apple TVs and unprotected .aac which will play on any device which supports the .aac format (you'd need to check the documentation for your device). The only other thing you can do with protected .aac files is to burn them to an Audio CD which you can then use as you would any other Audio CD.

You should be able to drag track in supported formats directly for iTunes to the mounted card. You could also do it through Windows Explorer.

Best of luck.
