This might help:
I saw that yesterday, but the entire list invalidated itself by saying that “California Girls” by Katy Perry is the #1 summer song OF ALL TIME. No way.
These are three of my summer favorites (yeah, I’m old):
Summer War, 1976
Hot Fun in the Summertime Sly and the Family Stone, 1969
Summer Breeze Seals & Crofts, 1972.
See You in September, The Tempos (original, IIRC) or The Happenings (original cover)

Sunday Shining- Finley Quaye
The Otherside- Breaks Co-op.
Leon Russell—Back to the Island.
