Very constructive reason...
Anyway, the whole point you have to comprehend is to stop ranting and bring some arguments and suggestions. There are a ton of people who like to whine, however their usefulness tends to zero.
Also, I still didn't understand why do you use this product if it gives you so much pain? Did you hear about "choice", "variety"?
Anyway, for you. Here are some actual reasons that everyone knows but you seem to need spelled out to you
Here's exactly what's wrong with the music app. Aside from speed which I have already mentioned, Xbox Music has a ton of little downgrades that add up to an overall maddening experience.
Firstly, they've fudged up the system so that MpaTool doesn't work anymore. You can't change artist and album pics anymore. Actually, that's not quite right. You can change Artist pictures but the music app will choose to ignore it. Even if the live tile is set to show artist pics if Xbox Music does not have an artist picture for that artist and you do XBM will still ignore it and show that stupid gray tile. Album art is a lottery, Either it shows up or it doesn't. If it shows up, it could still vanish when you change the song.
The music lockscreen is virtually gone.
Smart DJ to create autoplaylists for local music? Gone.
Viewing newly added music? Gone..
Gapless playback...ahahahahhahahahahaha
Most played? (A feature which my Nokia C3 had when I was in secondary school. I've currently finished secondary school and sixth form) Nope.
Recent music? Replaced by that idiotic recent plays that is as reliable as a condom full of holes
What have we gained? We've gained the ability to create playlists and scrub. In A year. That's absurd! That's f@?king insane!
