How to upload my music without using iTunes for my old iPhone?

I've been having problems with iTunes and uploading music from my CD's. It freezes up every time and I have to restart the computer to stop iTunes. Is there anything I can use to upload music from my CD's to my old iPhone? I'd like to use it as an iPod/iPod Touch?

Unfortunately all i phones and i pod touches have an encrypted music file system that requires I tunes to add music. I hate apple products for this specific reason. No simple use.
