Below is a list of OPs I think should be on the list, or at least should been considered. They are more or less in airing order. Of course as I get closer to the present more obscure shows and such are easier to remember. I just went through a seasonal list and wrote down the ones I kind of remembered being good.

I'm not sure which Bleach and FMA BH OPs aired during the decade.

Both of the original DRRR! OPs
My Soul Your Beats (Angel Beats)
Both K-On S2 OPs
All of the TWGOK OPs
Both Nichijou OPs

Platinum Disco (Nisemonogatari)
Try Unite (Rinne no Lagrange)
Both Aquarion Evol OPs
Real World (Humanity has Declined)
One of the Sword Art Online OPs
Sparkling Daydream (Chuu2)
One of the JoJo OPs (Personally I think Bloody Stream is the best one)
One of the PsychoPass OPs (I think Out of Control is the better one but both are good)
