One of the biggest progresses in a while has been that songs finally have their credits displayed, but this should be conveniently available on all platforms. Clearly it ain't the major part of users which are interested in this feature, but I can sincerely assure that hundreds thousands of us are still interested to see the names of the artists who bring all this music for the world.

It's now possible to check out the song writing credits on songs. To take a look, just right click on desktop or click the three dots on mobile on a song and select 'Show Credits'.
