Still problems streaming from certain artists

I am still running into streaming issues with the Cloud Music app on my Meizu MX4. Recently I noticed that certain songs from the band Megadeth can't be streamed anymore. They worked in previous version of the app. Basically the whole Peace Sells (2004 remaster) can't be streamed. Trying to download a track works but what is downloaded cannot be played. doesn't seem to be a valid mp3 file. If I try to import a file into the Music app on Ubuntu Touch it can't find anything. Similarly track from the artist Tsuneo Imahori and his Trigun soundtrack can't be streamed either and downloading doesn't here you get a track not found error when trying to download.

Finally my last issue is the fact skipping tracks manually doesn't work when you are on 4G/LTS or 3G. Jumping to a different in your playlist just breaks the app and you have to relaunch it for playback to work again. The artwork etc. is loaded for the track you have chosen but it never plays. The tracklength isn't displayed either you get 0:00.
