Noah, are you seeing this on Music Search?

If so, that's by design in that music search is not case sensitive and converts everything to allcaps.

Dean, care to comment? Should we be removing the shift key for some keyboards?

Yes, this behavior was seen on search under My Music. Even if the software is not case sensitive, it is a disconnect between what you press on the keyboard and what appears in the text field...

Yes, if the field only allows a limited set of characters, only those characters should be available on the keyboard.

That said, we shouldn't necessarily limit the search to uppercase only.  Let folks type in what they want.

I think Dean is reinforcing my point, however, if a user types in a lowercase letter they should see it that way in the entry field.  We can use the software to allow people to enter it in any format and still work:

eg./
The Rolling Stones
or 
THE ROLLING STONES
or 
the rolling stones

All of these entries should be acceptable.  By extension, the below entries should be acceptable as well:

Rolling
or
Stones

I'll make this right, but I just want to be clear that the root of this particular issue is on the SC/SN side-- the ALLOWED_CHARS string that comes from SC/SN for search contains only uppercase characters, and that is the only situation where typing on lowercase chars will show uppercase chars.

Regardless, it's wrong, and I will fix.

Keep the shift key and force case on the server side.  May I also suggest that the search keyboard should first appear in lower case, consistent with all of the other alpha keyboards.
