I don't get it, aren't most of your songs on sngle artist albums? Or are you saying you have 4,000 one off songs? You are aware that single artist albums show up as one cover right?
The only issue I've seen with coverflow is sorting by artist name, which leads to compilations containing various artists to show as individual albums with cover art. Now if you have lots of these types of albums I can see how renaming might be considered a hassle. For me it just takes an extra minute or so to select the entire group of songs, make group changes as needed, and move on.
It really doesn't matter if your'e all miffy about this issue or not. I agree it's a personal preference issue or matter of opinion.
What I'm seeing here is a lot of people piling on an issue and many of them expressing a desire to return their unit as somehow "defective" due to this issue (all or in part). To me that's just nuts. My ipod performs just the way apple's web site said it would. It has the features I expected based on what I read. I sure don't recal any claim being made about the response time on the interface, the way it sorts my music in coverflow, or any other of the many "performance" issues I've been reading here.
The bottom line remains, it's an awesome little device. If you can find a better one, go for it. And let us all know about it to boot.
