Example Input: Question: Who wrote the single from The Cars' third album that peaked at number 37 on the Billboard Hot 100? Passage:Their third album, Panorama, was released in 1980. Although it peaked at number 5 on the Billboard 200 and has been certified Platinum, it was less commercially successful than its predecessors. A single, "Touch and Go", peaked at number 37 on the Billboard Hot 100. Their next album, Shake It Up (1981), fared better commercially, going platinum by the end of the year and spawning their first Top 10 single with its title track. 1984's Heartbeat City was the band's most successful, hitting number 3 on the Billboard 200. Its lead single, "You Might Think", reached number 7 in the US, with three more singles: "Magic", "Drive", and "Hello Again" reaching number 12, 3, and 20, respectively on the Billboard Hot 100. Their Greatest Hits album, released later that year, contained the singles "Tonight She Comes" and a remixed version of "I'm Not the One", and has gone 6x platinum. Their final album before their breakup, Door to Door (1987), spawned the single "You Are the Girl" which reached number 17 on the Hot 100; it was their last Top 40 hit as a band.

Example Input: Question: How many of the albums did Heartbeat Productions distribute? Passage:The band originated from a surf rock-influenced garage rock group, the Sanctions, in 1965. The Sanctions, which included James Lowe (vocals, guitar), Mark Tulin (bass guitar), Ken Williams (lead guitar), and Michael "Quint" Weakley (drums), recorded 12 cover songs on an acetate disc on March 27, 1965, in a home studio owned by Russ Bottomley. For their next set of recordings on September 29, 1965, the group, then known as Jim and the Lords, was joined by keyboardist Dick Hargrave, who left shortly afterwards to pursue a career in graphic arts. The songs went unreleased until Heartbeat Productions distributed the 2000 album, Then Came The Electric Prunes, which was commended for its good sound quality, considering the circumstances in which it was recorded. Back to a quartet, the band, while rehearsing in a garage, met a real estate agent named Barbara Harris. Harris had connections in the music industry, and introduced the group to Dave Hassinger to record demos at Sky Hill Studios. Hassinger, who had been working as the resident sound engineer at RCA Studios, recently completed development for The Rolling Stones' album, Aftermath, and expressed a desire to produce a record. He suggested to the group that they change their name, and they considered a list of alternatives. According to Lowe, the name Electric Prunes started off as a joke, but he eventually convinced other band members, saying, "It's the one thing everyone will remember. It's not attractive, and there's nothing sexy about it, but people won't forget it." As a result of the recordings, a single, featuring a cover of the Gypsy Trips' folk rock tune, "Ain't It Hard", and the Lowe-penned song, "Little Olive", was released in early 1966, but failed to chart.
