486 - Steppenwolf Born to Be Wild 1968

Steppenwolf is a rock band of Canadian origin that started in 1967 and is best known for the hit "Born to Be Wild". The song is frequently described as the first heavy metal song ever written and is also said to have inspired the name of the emerging heavy metal genre; although these claims are disputed, the song's second verse (which refers to "heavy metal thunder") contains the first recorded reference to "heavy metal".
