Bluebulb Projects' The Measure of Things presents:
4,500 is about fourteen-and-a-half times the number of Beatles Songs.
In other words, the count of Beatles Songs is 0.0685 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.
