Bluebulb Projects' The Measure of Things presents:
390 is about one-and-one-fourth times the number of Beatles Songs.
In other words, it's 1.26 times the count of Beatles Songs, and the count of Beatles Songs is 0.794 times that amount.
(a.k.a. The Beatles) (1958 thru 1996)
On a total of 58 albums, the Beatles recorded 309 songs during their performing career (with three of the songs released only on post-breakup Anthology albums after 1970). Of their catalog, a total of thirteen songs were number-one chart hits in both the US and the UK.
