Because Sundays just aren't Sundays without Merlin being involved somehow.
The aim of this game is to nominate a song that you associate with a character, episode, ship, or just the show in general. You may nominate more than one in each category. Because filesharing is illegal, I recommend that you link to a youtube video, or playlist file, if you wish to share a preview of your nominated song. Please specify if your song contains explicit themes or language, so you don't frighten the chilluns.
