Genres are useful And needed for music lovers
As someone listening to most Genre - whether RnB&Soul, Hip-hop& Rap, Rock, Electronics & Techno, Pop, Jazz, Blues, Samba Funk, Folk, Acoustic and many more - depending on my mood of the day.
On some weekend days i switch genre and go through 4 different genres...
especially to enjoy several new tracks from different fields.
There is still all freedom to switch between all genre - that freedom is not taking away - the whole field of music is just more structured to get specific sounds faster.
Maybe a parallel page would be possible - or at least the options somewhere to listen through genre.
I agree with a user saying genre are also helpful for artists to target potential fans.
They are also important to people with limited time each day
- so basically to everyone .
