Because you didn't mention what mode of your iPod, I googled a post for you: How to Reset iPod nano and iPod shuffle . May it is helpful! Good luck to you!
Use some cleaning tool to remove cache and junk files from your iPhone. And restart your cell phone when it is very slow. It's my personal experience. lol
Hey, Miriam! To be honest, you can't transfer the music from the old iPod to your iPod 5 directly without outside help. If you do want to move the 200 songs to your iPod, you can make it by buying some third-party software which allows you move music from one iDevice to another iDevice without iTunes account. Here is a guide about how to transfer music from iPod to iPod. Absolutely, it also mentioned an iPod music transfer tool named AnyTrans. Anyway, buy a software or give away those songs!
