On March 2, 2008, the albums "Ghosts I-IV" (1 to 4) came out. It was made of 4 small albums Ghosts 1, 2, 3 and 4. All the songs on these albums were instrumentals and the first album was free to download from the website, or available cheaply to download. This was new in the way that music is sold, because usually music is sold for lots of money, and the money is given to many people, most who did not make the music, but helped give money to the people who did, or sent the music to shops to be sold, or made adverts for it.
