This is in my opinion probably the best internet meme out there.
It consists in making people sing using a tool called “Auto Tune”, a very used effect nowadays. People say that it started with Cher‘s Single “Believe”, and many artists like T-Pain, Chris Brown and many others started using it.
This first video i’m showing was the start of this meme, it was made as a tribute to Carl Sagan, the result was pretty interesting.

Eventually people started autotuning the news and things got out of control, because even boring stuff gets fun with auto tune

Auto-Tune the News #2: pirates. drugs. gay marriage.

…and Infomercials, i really enjoy this one as it transmits a very happy vibe, and i really dig the scatman part.

This is one of my favourite tunings, Kanye West and some popular kids on youtube get auto tuned
