I would suggest adding an “All” option when sorting a user’s ratings where you can usually sort by albums, EPs, singles etc.
I’m not sure if others feel this way but personally I like to look back on the best releases of the year and see how they stack up against each other, not just albums. Usually I put together a best of year list which includes EPs, one off singles, mixtapes etc along with albums. I’m sure for example there are plenty of people for whom Slow Riot for New Zero Kanada was the best release of 1999, or for whom Acid Rap was the best of 2013. It’d be nice to be able to have a complete list on this site of all ratings so one could see how particular albums stacked up against EPs, mixtapes or singles.
