Spotify premium on pc; high res selection help


Can 't figure out how to select the higher res rate on my brothers pc as spotify premium has a totally different interface on his pc than my iphone. I can't find any "settings" or "preferences" menu. I also can't find the option to download tracks for availability for offline listening. Any help is greatly appreciated!!

Spotify Premium offers better audio quality for users rather than free Spotify users. But please be not sad, you can use Spotify DRM Removal Tool for Mac to get Spotify Premium free and customize Spotify 160 kbps to 320 kbps with changing sample rate as 414,000 Hz for better quality. 
Just have a try of this. Listening experience could be better. For more, please visit: AudFree
Spotify is in 160kbps bit rate, this is not as high as the premium subscription 320kbps. And it is still lower than lossless 1411. If you’d like to find out how to reset spotify bitrate, you can use the DRmare spotify audio converter.You can change the bit rate as well as customize the output format and so on.
