I sent feedback through multiple portals. We'll see. I also wrote to "
The Next Track," a podcast co-hosted by Doug of Dougscripts to see if they have any insight. We'll see. If you PM me I have an email address you can also try.
I have 31,000 songs in my library. I rely on smart playlists to help manage my iPhone, which can't contain them all. One main way to do that is that I sync all my five star songs (ones I love) and many of my four star songs (ones I like) plus a smaller mix of three star songs (ones that are okay but I have friends who really like so are handy to have easy access). As to one and two star songs? Sometimes you buy a stinker. I don't sync them but I don't delete the files in case I forget I ever bought it; keeps me from buying it again).
Now, you may say that that's cumbersome or not necessary but keep in mind that many users have incrementally invested a lot of time in systems that work for them. In my case simply removing the star rating feature will mean suddenly having to do a *lot* of work (maybe using tags or grouping) but until that's done syncing and backing up may be inadvisable. Unless there's a very good reason to wipe out this feature it seems deeply consumer unfriendly to part of their customer base.
That's pretty dismissive.
(Hint: for you it is and that's fine, but you are not everyone.)
