Sunshine Pop

Sunshine pop (originally called "soft pop") is a lightly-produced pop style influenced by commercial jingles and easy-listening, usually incorporating acoustic guitars, vocal harmonies, bossa nova rhythms, and (occasionally) lush orchestras. It originated from Southern California in the mid 1960s, and was most prominently represented by the Association, the Mamas & the Papas, and the 5th Dimension.

The genre is often erroneously thought of as "Beach Boys-style music" or "music with sunny themes".
