I am from the generation that grew up on cassette tapes and walkmans, then transitioned to the MP3 phase. Most of the music that is in my CD collection is available to stream through Amazon music, but there are a few things that I have on CD that are not. I managed to put my entire CD collection on here (I had somewhere in the neighborhood of 300 CDs before I stopped buying them) before iTunes stopped the ripping from CD capability. You can still use this version of the iPod on iTunes, but you have to rip CDs using a different service and then transfer the MP3 files over to it. So, getting music onto the older iPods like this is not as easy as it used to be, but is still doable. The pros of this model are that you will be able to get at least a good chunk of your CD collection on it (depending on how many CDs/MP3 files you have and if you get the model that has 160GB or more or storage space) and it has pretty good sound. And, assuming your vehicle still has an AUX port, you can plug it into that and play all your music in your car.
Some of the cons are, i) it does not have Bluetooth, so you will need corded headphones, ii) it is fragile, so you definitely want to find a case for it because if you drop it on a hard surface, it can easily break, iii) it has no internet connectivity, so to get music onto it you will need to plug it into a computer.
So, if you are in your late 30s and up, and still have CDs, but don't want to lug the CDs around anymore (assuming your car still has a CD player in it) and don't want to fill up your phone's storage space with MP3 files, this is a good option. If, however, you do not have a CD collection or you do not have a bunch of MP3 files on your computer that you want to be able to take with you, this is really not necessary.
