However, the lead single was what grabbed the attention of both fans and the music industry. "Smooth", a dynamic cha-cha stop-start number co-written and sung by Rob Thomas of Matchbox Twenty, was laced throughout with Santana's guitar fills and runs. The track's energy was immediately apparent on radio, and it was played on a wide variety of station formats. "Smooth" spent twelve weeks at number one on the Billboard Hot 100, becoming in the process the last #1 single of the 1990s. The music video, set on a hot barrio street, was also very popular. "Supernatural" reached number one on the US album charts and the follow-up single, "Maria Maria", featuring the R&B duo the Product G&B, also hit number one, spending ten weeks there in the spring of 2000. "Supernatural" eventually shipped over 15 million copies in the United States, and won 8 Grammy Awards including Album of the Year, making it Santana's most successful album.
