I want to make it so that on my ipod, I choose which artist I want to hear, and then which album, and on to which song. How do I do that?
You just have to make sure your ID3 tags are correct.
and then it will group them into a flow like artists>albums>songs?
Yes, the iPod will set that up according to the Id3 tags.
I will also add that it is very easy to make sure the ID3 tags are correct through iTunes. You can customize to your liking.
