Seems like you just found an excuse for your unnecessary invectiveness. You probably think you’re funny or you’re trolling. This is not even trolling, not even fourth-class bait material. Maybe you should try Kali, suits your attitude more.
I have Nano 7 as well and I tried many things over the years. However there isn’t a good solution to this. I have a Windows 7 VM just for my iPod and installed an old iTunes just to put music on it. You can use Gnome Boxes for this job.
Once you installed it, start the VM and plug in your iPod. For VM to see it, on right top there is a … menu, go preferences from there. Switch to Devices & Shares tab. It should see your iPod now, just enable it. Also set a shared directory from below so you can put your music files there before uploading them to your iPod. This is the iTunes version I use: www.filehorse.com/download-itunes-64/35820/
I don’t know if there is a unified tool for that but I use btop and nvtop side by side. I don’t really care but if there is one, I’d like to know as well.
