Which song from today will be considered a classic in 2045?

Spotify asked this question in an ad and it had me thinking which songs from 2005-2013 could be considered a classic to the future generations. I couldn't think of many so I decided to ask you guys here. It can be a song from any genre of music but you can not be bias a choose you favorite song/band by default. Please explain why and also a video or link of the song would be nice. :)

I believe any justin bieber song will suffice

I don't think any of these will be considered classics.

ComicVine is full of hilarity -- each post was stellar in that regard.

In an attempt to take this thread seriously, I am going to submit the following, but the acoustic version:

Look up any cake or radiohead song.

Smoke on the Water.

Okay seriously............ also one of the sexiest songs ever.

Muse - Knights of Cydonia

Unfortunately,Call me Maybe.

I think the Singles from Fun. Some Nights album.

Anything from Coldplay.

Also...

Amy Winehouse's "Back to black", and maybe also "Rehab".

But seriously:

Maybe something by Jamey Johnson.

Really liking some of the answers lol.

Let's be honest, guys. We all know it's Michael Buble and that fat chick who will live on forever.

Anything by Gotye

Sexy? This is depressing as hell.

They should change the title of this thread to spot the hipster........
