Lady Gaga was still hot in 2010, especially with the release of Fame Monster (a compliment to Fame). The album had many great tunes, but my favorite, and the song of the year for 2010, was not released - "So Happy I Could Die". This song was probably my favorite because the sound/beat is similar to Kanye West's "Flashing Lights" which had won the award a few years previously.
I love how the song builds with that exceptional electronic beat. It is complimented with Gaga's great voice. The result is an excellent dance/disco/electronic/pop tune. It is a shame it was not released. There is no video so you get some individual's pics to the song.
