Song or Artist Help please?!

Ok so I heard this kid at school play a song on the bus and it was an actual song, he said the artist or the name of the song was something that sounded like "def pine" or "dafhine" but it IS a real techno song and I think it's pretty popular! Please help me find it, as always 10 points will be rewardedWww@Enter-QA@Com
