I replaced the battery in my second hand first generation iPod maybe three times over ten years.

Then for a number of years I used a late generation Zune that I got new at Walmart for a steal.

Now I use Spotify on a smart phone, and it's a slow web app full of ads, delayed page reloads, unnecessary videos, and a buggy seek widget. The only controls are a touch screen.

It is convenient to have my music player in the same device as... wait, all I wanted was a music player.
