The European Dance Radio Chart (also known as European Dance Radio Top 25) was a weekly chart compiled by pan-European magazine Music & Media. After dance music had played a more dominant role on the magazine's Eurochart Hot 100 in the beginning of the 1990s, the new chart was launched on 28 September 1991.[1] Based on a weighted-scoring system, it was compiled on the basis of playlists of European stations programming various styles of dance music, including hip hop/rap, R&B and swingbeat, for the 15-30 year-olds, fulltime or during specific dayparts. The first number one single on the EDR Chart was "Gett Off" by Prince.
