Quick, pick your favorite song of all time!

Hey crew.

As the title says, pick your favorite song, track or tune of all time. Just one song, no tied number ones, no songs longer than 15 minutes. GO!

Mine:

My opinion on this subject changes alot. So for today it would be this:

How many song topics do we need right now, seriously?

Right now? A Day In The Life.

EDIT: Also, there are songs longer than 15 minutes that definitely deserve to be in here. In-A-Gadda-Da-Vida at 17 minutes and 40 seconds instantly comes to mind; the 20-minute version of Whipping Post and the 45-minute version of Whole Lotta Love come up next. They are very definitely one song, and they are very definitely excellent.

Lady Gaga - Bad Romance

"Ignition (Remix)" by R. Kelly

This article sort of explains how I feel.

At this point it's time to flag these because you didn't even attempt to search the forums OP.

Best use of a car horn in any song, ever.

Bad quality, amazing interpretation; not technically a song; don't care

I can't really explain why, but:

Also, I prefer the extended version, but it's basically this song.

Muse - Bliss

Melodic wailing and pure aggressive evil. Twenty years ago thought I'd outgrow this stuff. Hasn't happened yet.

Your pick.....came out of left field.

Leftism was a great album. My fav song of all time is...shit, ummm. Yeah, it'd have to be Propane Nightmares by Pendulum. While I'm typically a metal guy, everything about that song just speaks to me.

Go fuck off with your 15-minute limit. Echoes is my favorite song of all time.

i dont really have a favorite song, is that bad? 
  

@TimedExposure: Beautiful one that.

This has died down now but there have been a fair number of these song topics recently. Not only was this arguably a duplicate thread but the forums are meant to be a place of meaningful discussion, and threads which just start with the posting of a YouTube video and a few words of text, or threads that encourage people to post YouTube video after YouTube video without any real discussion, are not what Giant Bomb is here to facilitate. Thank you.
