I don't think this is often talked about, but Music In The Simpsons have been described as Serious and Emotional rather than Cartoonish. In fact, the classical music we hear in The Simpsons is one of the big things that makes The Simpsons feel touching, a serious impact, saddened, light hearted, or a better description realistic that can happen in everyday life, examples of famous scenes such as...

Maggie's First Word "Daddy", or Michael Jackson's "It's Lisa's Birthday", JFK Theme at the end of "Who Shot Mr. Burns Part I", or the lovable but sad scene in Mother Simpson, where Homer saw his mother left and than later he's gazing at the stars wondering what she's doing now.

In fact several of the composers that made this beautiful music, sound effects originally did not want to be on The Simpsons, because they thought it was cartoonish, but Matt Groening explained that they need the serious kind of music that has an impact on the Character's lives, and so it happened. Now this brings into the question to fans...

What kind of composer, musician, genre, or music you would want to see in an later episode? Better yet, describe how the scene should look like during the music if you want?
