The account is now hosting a "World Cup" of evensong anthems, and after much discussion and preliminary voting, the two page list below has been put together. Voting has (only just) begun, and there is a pinned thread to explain the process here.
Because I obviously don't have anything better to do (what could be better than listening to hours of evensong anthems?!) I have put together a Spotify playlist of all but the most recent compositions which are yet to make it to Spotify. You can click the image below and it should take you to my playlist, which is public. I found most of the missing anthems on Youtube with little effort - I highly recommend Sarah MacDonald's "Crux Fidelis" which is on Soundcloud and Anna Thorvaldsdottir's "Heyr þú oss himnum á".
