[March 2015 update: site renamed Music Industry Data]
ACO is a new subscription database which includes over 60 years of popular music charts from the Americas, Europe and some Asian territories. Data is provided by Billboard, The Official Charts Company, Aria Charts and other similar sources.
Searching is possible by artist, single or album title, date, label, and chart position. Sophisticated tools then allow you to interpret, graph, analyze, compare and contrast musical trends and interactions. For instance you can chart the performance of Adele’s album 21 in the US, UK, and Australia. You are also able to superimpose graphs from different artists, countries and formats and display them in absolute or relative time. The instructional videos on the web site may be useful in learning how to use the graph function.
Most tracks and albums have audio samples.
