50 Cent "Ayo Technology" (2007)

Crystal Castles "Courtship Dating" (2008)

Where They Sound The Same: When 50's intro is over and the beat drops at :28, it sounds just like the beginning of "Courtship Dating."

It's likely that Timbaland and Ethan Kath both used 8-bit sound module Elektron SidStation to produce the similar synth sound on both records. This initially lead to some minor controversy, but it's been mostly accepted that this was just a major coincidence.
