A lot has changed since 2007. The iPhone was still in its first generation, Barack Obama was an energetic young senator, and you still had a Facebook wall.

Things get even crazier when you explore the top-selling music.

On iTunes, 2007 was all about Amy Winehouse, Kanye West and Rihanna. But the Billboard year-end album sales list looks a little different. With two Disney Channel soundtracks in the top 10 on Billboard’s year-end album sales chart and Justin Timberlake at the height of his powers, it was a completely different world.
