8. "Brown Eyed Girl" -- Van Morrison (1967)
Everyone has cherished memories of young love which is one reason Van Morrison's "Brown Eyed Girl" remains so popular more than 40 years after its recording. The Irish singer's first single after leaving the band Them stirred some controversy with its line "making love in the green grass" which was changed for radio play but made it all the more memorable. The nonsense lyric of the chorus -- "Sha la la la la la la la la la la te da" -- makes it chant-worthy to this day, although Van Morrison himself has declared it's not his favourite song to sing.
