Polish music charts
This chart was compiled from actual sale figures as reported by over 130 music shops across Poland and included both albums and singles.[2] From October 1994 to September 1997, journalist Artur Orzech presented a weekly top 20 albums list on Radio Bis which was later extended to 25 and 30 positions.This chart was also based on actual sales data obtained from about 150 music shops, including albums as well as singles as opposed to being two separate lists.[2] The popularity of individual songs has always been reflected by radio polls and hit lists, compiled from the listeners' votes.The single format has been somewhat substituted with cardboard records which were produced on a massive scale and sold in large quantities.
