What do stars mean that are opposite the name of each track in sections Hot tracks and Cool tracks?
For the songs that are quite a long time on our site one star means that a track was at least once among a hundred of the best songs, two stars mean that a track was among a hundred of the best songs at least for 4 weeks, three stars mean that a track was among twenty best songs for 4 weeks. Stars are often given to the tracks that appeared on our site several days ago. We taught our system to forecast the possible chart history of a new track. The forecast is performed with the help of a unique model and it takes into account a lot of factors: the quality of the previous tracks of this artist, chart parameters of these tracks, general parameters of a new phonogram, its format, the first reaction of radio stations etc. So, the system of track ranking with the help of stars allows the musical editor to define the most popular tracks or the tracks that are likely to become popular in the next two or three weeks literally at first sight.
