Question

Hello.I have a problem when I want to sync from iTunes to my iphone 5s.I've already authorized my computer from iTunes but when I want to sync,the error message will appear which says you must authorize your computer

Answer 1

Perhaps I have to click 'apply' to this setting for it to take the desired effect,
Yes, you do need to click Apply.
but I simply don't want Autosync - my library's too large for my Nano.
It's not a problem. I have ~30GB of music and a 4GB Mini & I use Autosync.
Select the iPod.
Click on the Music tab.
Select Sync selected playlists.
Then I add/remove from these playlists, plug in the iPod and it syncs.
All ratings, last played, etc. get transferred.
This was indeed how the shuffle toggle worked a few updates ago
I've never heard of "shuffle toggle". Do you mean you are clicking the shuffle bottom ot th bottom of iTunes?
Are you using an iPod Shuffle? Do you mean the Autofill on the iPod Shuffle?
Autofill is only on the iPod Shuffle. It isn't on the other iPods.
and I came to appreciate this feature. Since it's removal,
Again, not sure what "feature" you think has been removed.
I've been seeking a functional work-around.
Which is exactly what I gave you.
Thank you for the idea here, but manually choosing random tracks to create a special playlist of XX size is not only tedious, but defeats the true randomness I want back.
You do not manually choose any tracks. You can't even drag songs to a Smart playlist.
If you follow the steps above, it will create a playlist of the size you choose, with random songs from your library.
You can set (or not) the criteria you want, such as not longer than 4 minutes, or of a certain Genre.
Do you know of an email address I can send some of my questions directly to Apple's team - maybe specifically their software development group?
You can send feedback & ideas here -> http://www.apple.com/feedback/itunesapp.html
but you will not receive a response.
