Rihanna - Don't Stop the Music
Not really a great song. The song is somewhat flat. The melody is also flat. The music video is also lousy. It just repeatedly display her beautiful eyes and face.
Don't Stop the Music, Virtuoso Piano
Great performance. Though, i don't particularly find this composition attractive. It lacks a strong melodic element, despite the fact that the original song already isn't noted for its melody. Nor does it have a strong theme that ties it together.
Though, i think it is a good composition. These days, you don't get much of these type of composition anymore.
