The Beatles used the word love exactly 613 times in their songs.
For some added trivia:
613 is a prime number, the first number of prime triplet (p, p + 4, p + 6) and the middle number of what’s known as a sexy prime triple (p − 6, p, p + 6); and
613 is an area code assigned to the province of Ontario in Canada – one of the original 86 area codes created by AT&T and the Bell System in 1947; and last but not least,
613 is also the number of commandments (mitvot) in the Messianic Torah in Judaism.
