重金 can refer either to a large amount of money (usually in the context of investment, recruitment, or bribery) or to the heavy metal music genre. The two senses are unrelated. In the financial sense, 重金 is often used in formal or business contexts such as 重金悬赏 ('offer a large reward') or 重金打造 ('build with huge investment'). In the music sense, it is a loanword from English and appears in phrases like 重金属乐队 ('heavy metal band').
