David Bowie's death came as a shock to the world. As a fan, I spent the following week listening to Bowie's music nonstop. While most people have heard the more popular songs such as: "Changes," "Heroes" and "Space Oddity," there are so many more songs by David Bowie that deserve more recognition.

Here is a list of some of the icon's most underrated songs and ballads.

1. "Slow Burn" (Heathen)

Featuring Pete Townshend from The Who on guitar, Bowie received a Grammy nomination for Best Rock Male Vocal Performance in 2002.

2. "Janine" (Space Oddity)

3. "The Stars (Are Out Tonight)" (The Next Day)

4. "Be My Wife" (Low)

5. "This is Not America"

This song was featured on the soundtrack for the film "The Falcon and the Snowman."

6. "Lady Grinning Soul" (Aladdin Sane)

7. "Wild is the Wind" (Station to Station)

Bowie's cover of Johnny Matthis' song is fantastic.

This song was originally recorded for Paul Shrader's 40th anniversary remake of the film "Cat People" (1942).

9. "Quicksand" (Hunky Dory)

This song introduces Ziggy Stardust, one of Bowie's famous personas, for the first time.

David Bowie was one of the greatest artists of this generation who inspired a lot of people to discover themselves. May he rest in peace.
