Not sure if I should migrate to Ubuntu before knowing if I won't be using the iPod or not

I have an iPod Nano 7th gen which I use frequently especially when I workout (I know it's outdated but I don't like the phone because of distractions) and I wanted to start using Ubuntu instead of Windows. I already know there won't be iTunes in Linux but I've read that there's another app called Rhythmbox that could sync iPods. Thing is, I read positive outcomes from people just like the negative, failed attempts. Any help?
