16GB iPod Nano 3G Upgrade

The iPod nano 3rd generation holds a special place in my heart, i was about 14 when my mom bought me one as a birthday gift and i still cherish it till today where I charge it maybe once a year and list to my (very curated) metal catalogue from back in the day... it was the only ipod i ever had or needed

It obviously can't hold a charge anymore and every time i reach for it i'm praying it still works
