Songs of the decade

Heard some music tonight that took me back a few years, and I started thinking of a short list of songs that stand out from the past decade. Nothing too obscure here, these are just the hits that seem to represent parts of the last 10 years, in quasi-chronological order:

• St. Germaine – Rose Rouge
• The Strokes – Last Nite
• Outkast – Heya
• Neko Case – Deep Red Bells
• MGMT – Time to Pretend
• M.I.A. – Paper Planes
• Bon Iver – Skinny Love
• Cloud Cult – Everybody Here Is a Cloud

Interestingly, the artist/album that I would say is the biggest stand-out for me from the zeroes is Arcade Fire/Funeral, but that album truly worked best as a single entity and there’s isn’t one single off it that I would pick out for the above list.

I can only wonder now how these songs will endure, and what new sounds the upcoming decade holds. Do you think music reflects the mood of the time in which it is created or more so contributes to that mood? Cause or effect?
