Yep and also when you’re log in and “share” a song, it’ll be bind to your account so that you can easily look for all your songs or see others songs.
I though too to add a “Remix” thing, like when somebody modify someone’s else song he is still credited for this song and you can also search for all song that were based from that original song (sorry I know it might not be clear but it’s late, goodnight ! )
How about a Featured Songs genre? You could make the Featured Songs page just display the last 16 features because it doesn’t really make sense to me to have 6+ pages of featured songs.
There will be featured songs (not a genre), and you will be able to filters them by genre, they will be displayed from most recent / listens count / rating / etc.
