Apparently now you can access these pages for songwritters in the credits section of any song in Spotify. There are a lot of writers or producers that are not included yet but it's a nice thing to have.

Ah, finally something better than the sloppy allmusic.com database is coming with this feature. I'm very happy with this innovation.
Spotify is very sloppy in comparison with Tidal where you get the complete discography of everyone. Spotify's page looks manually-made.

You can also sort by year and filter by production or instrumentation. The downside is that every cover uploaded counts and it floods the list of everyone.
Thaanks for pointing out the Tidal one as well. I'm just waiting for a proper list of all Denniz PoP songs, so that I can start to analyse his development.
In the post on Spotify blog said those pages are maintained by a composer (record label) and I think that's why not all songs are included...
They have all the metadata available, it's so weird the way they're handling it.
