Artists not appearing under song title

99% of the songs in my Music app I’ve transferred to my phone using iTunes, and i’ve noticed that whenever i play these songs the artist doesn’t appear. However, when a song is played straight from Apple Music, the artist will appear!

Start by reproducing the difference between iTunes-transferred songs and songs played from Apple Music on a phone. Then locate the app's song playback and artist-display entry points; the issue mentions no files or tests. Done means the artist appears consistently for transferred songs as well as Apple Music songs.
