You seem to have really got something here, Joorin, and it's come on really quickly too.

Seeing your comments on 'screen estate' I had an idea for representing 'popularity' without using space: could you signify 'popularity' by the colour of the text (perhaps from a 'hot' red tone to a 'cold' blue)?

Having said that, the ability to sort by column makes spotify work so well - including sorting by popularity, (handy when you're checking out hitherto unknown artists) - so assuming you plan to add the column-sort functionality at some point, maybe my idea wouldn't work - but hey just thinking aloud.

Thanks again for a great piece of work
