he left out what I was talking about. 50 cent or who ever produced the song "ayo Technology" sampled from Crystal Castles.
Doubtful. There is actually no controversy as far as I can tell. Both songs have a similar sounding arpeggio, but if you listen carefully, the one on "Courtship Dating" sounds sampled. The one on "Ayo Technology" sounds more like a "natural" SID sound (Timbaland has a SIDstation, Crystal Castles don't or didn't at the time they made their song). Plus CC are known for their heavy use of samples.
