The Song of the Day (SotD) is a fun way to get exposed to some new music, or maybe learn more about a song you already know.
The way it works is this:
Anyone can nominate a song on the Song of the Day special page. Once approved, the nominations are then moved to the queue. One nomination is then selected each day from the list of songs in the queue and displayed on the LyricWiki Main Page as "Sotd". The nifty badge on the right is also added to the song's page.
The successful nominee isn't forgotten about either. Providing they are registered (and don't use an alias when submitting their nomination) they receive notification that their song has won "Song of the Day". Also, that their name has now been added to the list of SOTD Winners.
After the day is over, the entry is archived. The entry is also displayed on this page until the middle of the following month.
