Billboard Japan has revamped its Hot 100 chart, expanding its data sources and launching chart analytics service, effective on June 3.
Launched in 2008, the Billboard JAPAN Hot 100 currently combines multiple data sets including predicted nationwide physical sales from nearly 4,000 music and e-commerce retailers tracked by SoundScan Japan; digital download sales from Nielsen Music; airplay from over 30 major AM/FM stations monitored by Plantech; volume of desktop look-ups on PCs tracked by Gracenote Media; and Twitter mentions of artist names and song titles provided by NTT data.
I think YouTube views inclusion into chart formula is a good idea. Not sure about Twitter mentions. What do you think?
