Instrumental Theme Songs Per Decade

I have a theory that each decade can be defined by an instrumental song.  Here is my list:

1890s - "Stars and Stripes Forever" by John Philip Sousa
1900s - "The Entertainer" by Scott Joplin
1910s - none
1920s - "Rhapsody in Blue" by George Gershwin
1930s - "Sing Sing Sing" by Benny Goodman
1940s - "In the Mood" by Glenn Miller
1950s - "Where Is Your Heart" by Moulin Rouge
1960s - "Theme From a Summer Place" by Percy Faith
1970s - "Love's Theme" by Barry White and Love Unlimited Orchestra
1980s - "Axel F" by Harold Faltermeyer
1990s - "Forever In Love"/"Careless Whisper" by Kenny G
2000s - none
