Missed this - sorry, this isn’t quite clear in the mockup. You can click on the artwork column to play the album, using the ListenBrainz player. I imagine it would be hidden unless you clicked the play button (actually, I need to add a ‘close’ button to the player don’t I)
One thing I’m excited about is how things like this can have knock-on effects that are really interesting! If clicking the ‘play’ button at the top of a table plays through everything in there, it means collections and labels etc become something people can listen to. Cool. Cool? Cool. 
I’m aware not everyone will want this which is why it didn’t get its own column, just uses an existing one (but again, let me know if you still hate it)
Combining the ‘MBz ecosystem’ was one of my key aims in the ticket, which I should have put here:
- Ease of use for editors, without cluttering the display for casual users (editing tools at the top)
- Calls to action (big edit button at the top, big buttons for key actions on the side, various edit icons)
- Linking the MBz ‘ecosystem’ (sections leveraging and inviting users to LB and CB)
- every display, table, sorting, collapsing quality-of-life improvement I could think of at this time…
