So now that we're coming close to the end of 2009, what do you guys think has been the best anime song so far this year? This could be opening, ending, or otherwise but it needs to be from an anime that aired in Japan this year.

For me, hands down I'm going to have to say "Only my Railgun" by Fripside. This is the opening song to とある科学の超電慈砲 (To aru Kagaku no Railgun).

You can listen to it here: (And remember, Jesus watches Youtube in HD)
