"The Last Time", released in February, was the first Jagger/Richards composition to reach number 1 on the UK charts; it reached number 9 in the US. It was later identified by Richards as "the bridge into thinking about writing for the Stones. It gave us a level of confidence; a pathway of how to do it." Their first international number 1 hit was "(I Can't Get No) Satisfaction", recorded in May 1965 during the band's third North American tour. Richards recorded the guitar riff that drives the song with a fuzzbox as a scratch track to guide a horn section. Nevertheless, the final cut was without the planned horn overdubs. Issued in the summer of 1965, it was their fourth UK number 1 and their first in the US, where it spent four weeks at the top of the Billboard Hot 100. It was a worldwide commercial success for the band. The US version of the LP Out of Our Heads, released in July 1965, also went to number 1; it included seven original songs, three Jagger/Richards numbers and four credited to Nanker Phelge. Their second international number 1 single "Get Off of My Cloud" was released in the autumn of 1965, followed by another US-only LP, December's Children. The album Aftermath, released in the late spring of 1966, was the first LP to be composed entirely of Jagger/Richards songs; it reached number 1 in the UK and number 2 in the US. In a 2018 retrospective, The Daily Telegraph considered Aftermath to be most important of the band's formative records. On this album, Jones' contributions expanded beyond guitar and harmonica. To the Middle Eastern-influenced "Paint It Black" he added sitar; to the ballad "Lady Jane" he added dulcimer, and to "Under My Thumb" he added marimbas. Aftermath also contained "Goin' Home", a nearly 12-minute song that included elements of jamming and improvisation. The Stones' success on the British and American singles charts peaked during the 1960s. "19th Nervous Breakdown" was released in February 1966, and reached number 2 in the UK and US charts; "Paint It Black" reached number 1 in the UK and US in May 1966. "Mother's Little Helper", released in June 1966, reached number 8 in the US; it was one of the first pop songs to discuss the issue of prescription drug abuse. "Have You Seen Your Mother, Baby, Standing in the Shadow?" was released
