These things need to be fixed/added in the IOS app:

Takes way too long to boot up recently. 

No album year or number of songs or timing info on album info page. You hear a song in a playlist or radio, 
and you click on "Go to album" and you would like to know the year of the album but it's not there!

Album info view needs track numbers.
Needs time of track on all screens where the song is listed
Needs album name on all screens where title and artist is listed.

Shuffle needs to shuffle ALL tracks by the artist, not just the songs on the top 10. It is totally worthless
the way it is now.
When you are on an artist's page, it makes you tap on "see all albums". Just list all the albums right off the bat!! 
The whole idea is to limit the number of taps the user has to do to get to where he wants. That's basically
the problem with this new version - it takes way longer to do things than it used to.
Plus the large album art and two or three per page is unnecessary - one line per album is enough.

Buttons need to be more resposive. Since the update it has taken much longer for the app to recognize key presses.

Going from one song to another causes display freeze,
