On all versions of Spotify (mobile, PC etc.) the browse/search area is full of genres I have no interest in. For example, one of the genres on the page is 'Metal'. I will never listen to that and it takes up space on my browse page which I would far rather be personalised to me, by me.
If there was simply a move & remove option (kind of like apps on a phone homepage) with removed genres that could be restored by maybe a "genre" on the browse page called 'Removed' which I could click on, showing the genres I deleted from 'Browse'.
