So far so good with 8.0 except the music player. I cannot imagine what they were thinking. I can only guess nobody ever tested this UI with anything but streaming media. Like many owners, I have a USB stick in my car with several thousand songs on it. The old music player UI browsed these well -- the player certainly had annoying bugs, like unpausing every time the car woke up, but the player could be used to play music. The new UI cannot be used to play music from this device. I mean, it is possible to play a single song, but that's about it. Why? Because the browsing has been totally broken. 1. If I browse by "Artist", I have to scroll down over 100 times to reach artists whose names start with "Z". Each scrolling operation (swipe) poses a risk that I'll accidentally click an artist name, and if I do that, when I go back to the artist list, my position has been lost -- it resets to the top and I have to start scrolling again! 2. When browsing by "Artist", once I pick an artist (probably one whose name starts with "A" -- see above) I am presented with a flat list of that artist's songs, not separated by album and not even in album order! I have not owned a music player with a bug like this since -- literally -- 2002. 3. Even if I give up and browse by "Folder" (lucky I organize my music into folders), even though I put the track number in every track name and properly tag my tracks with the track number, once I drill down to the folder for a given album the tracks don't play in order. This is ridiculous. I came closer than I've ever come to a crash in my Model S just trying to swipe the 100+ times required to play a song by Yo La Tengo. Who releases software like this without testing? The music player has been effectively removed from my car by these idiotic changes -- I guess this is the downside of over-the-air updates, they can break stuff you would have never imagined they could break, and make stuff you rely on like playing music in your car basically impossible. I wonder whether they'll ever fix this. They obviously don't care about it much or they would not have included this version of the player in the 8.0 release.
