B.o.B. "Psycadelik Thoughtz" Might Sample Britney Spears' "Outta This World" & Here's 7 More Songs That Sample Other Tracks

If B.o.B.'s new song "Psycadelik Thoughtz" sounds familiar, that's because it kind of is. The new track appears to sample Britney Spears' "Outta This World." (The snippet comes from one of the rare Britney Spears songs, but is still great.) While it's not confirmed that the sample is the Spears' track, it still adds an amazing layer to "Psycadelik Thoughtz."

"Psychedelic thoughts, psychedelic calls / From these psychedelic trees and I think it's rubbing off on me / I think it's rubbing off on me, I think it's rubbing off," B.o.B. raps as he questions who his real friends are.

He adds, "I'm searching for an outlet tryna charge my phone / Looking through my contacts ain't no one to call / Questions that need answers, looking for escape / I'm just looking for that high, can ya help me elevate?"

If you listen closely, you can hear similar beats at the beginning of both B.o.B.'s track and Spears' track. In both cases, the music adds a slightly trippy effect that suits both tracks. However, many artists experiment with sampling and some of our favorite songs include snippets of other tracks. Here are seven of the best songs that sample other songs.
