The Music Genome Project's database is built using a methodology that includes the use of precisely defined terminology, a consistent frame of reference, redundant analysis, and ongoing quality control to ensure that data integrity remains reliably high. Given the vector of one or more songs, a list of other similar songs is constructed using what the company calls its "matching algorithm". Each song is analyzed by a musician in a process that takes 20 to 30 minutes per song. Ten percent of songs are analyzed by more than one musician to ensure conformity with the in-house standards and

. The Music Genome Project was first conceived by Will Glaser in late 1999, and populated with musicological input from Tim Westergren in early 2000.
