PLUG

Think of a way to promote something enthusiastically, like a musician might do for their latest single.

Bang the drum for" is a playful hint where "bang" suggests hitting or promoting something hard, like a drum. The phrase also means to advocate loudly for something, which ties to "plug"—a slang term for promoting or advertising. The wordplay links the literal act of drumming to the figurative idea of pushing or "plugging" an idea or product.
