In 2000 a Finnish guy Janne Suni composed a C64-style music track ("Acidjazzed Evening") for Assembly 2000 demoparty, a competition in computer art, held in Helsinki, Finland (Later this track was remade by Glenn Gallefoss with Janne's express permission).
Fast forward to 2005. American hip hop and R&B record producer Timbaland releases a ringtone on MSN music ("Block Party"), which is exactly the same song with an added beat! In 2007 Timbaland uses the same exact track for a new song "Do It" as a part of Nelly Furtado's album. The similarity between music tracks is astonishing!.
Now, see (or, rather, hear) it for yourself:
Original MOD track (MP3 format)
2005's ringtone
Some people comment "hey, come on, this is sampling, that's what hip hop does all the time".
But this is NOT sampling, this [very naughty plagiarist] STOLE THE WHOLE FRIGGIN' SONG!
