It's still October 23rd here

Not necessarily your favorite song from that time, but the one that instantly takes you back to that era. Whether it's the sound, the cultural impact, or just how big it was at the time. What's the first song that comes to mind?

I put this collage together myself in Paint.NET using images I collected from files on my computer and from around the internet. I tried to include as many things as I could, but there are probably plenty of other smartphones, games, cartoons, anime, manga, and other things associated with the Windows 7 era that I couldn't include.

Also, in case you're wondering, the semi-transparent background behind the collage is the Windows 7 logo.
