Persona 4 is popular not only for its fun gameplay, intriguing plot and superb art, but also for its songs and soundtracks.
A local who goes by “rika” covers the opening theme song of the game. The anime also features the song.
As a Persona 4 fan myself, I would say this cover is fantastic.

If you love Persona music, do google up “Persona Music Live”, which was held in 2009 and 2010, and will be continuing its 3rd performance in 2012.
