The Project: Mobius Fab 50 - Week of October 17, 2011

Have you been watching X-Factor? If so, you've heard this song every time the ubiquitous Pepsi commercial comes on. However, Outasight's "Tonight Is the Night" is also premiering on the Fab 50 this week. Anyways (after an extremely long break), which song tops the Fab 50 this week? Read on for the chart!

Although "We Found Love" is still in 1st, 5 songs move up in (or into) the top 10 of the Fab 50 this week, meaning that it's definitely going to be difficult for Rihanna to get her 4th week at #1 with her Calvin Harris collab.

At the Top

• "We Found Love", by Rihanna and Calvin Harris, remains at #1, while Gym Class Heroes' "Stereo Hearts" uses Adam Levine's "Moves Like Jagger" to slide into 2nd.
• "Without You", by Usher and David Guetta, and "In the Dark", by Dev, move into 5th and 6th, respectively.
