"Just What I Needed" is a song by American rock band the Cars from their self-titled debut album (1978). The song, which first achieved radio success as a demo, took inspiration from the Ohio Express and the Velvet Underground. The song is sung by bass player Benjamin Orr and was written by Ric Ocasek. "Just What I Needed" was released as the band's first single in 1978, reaching number 27 on the US Billboard Hot 100 and charting in several other countries. Appearing on numerous compilation albums, it has become one of the band's most popular songs and has been received positively by critics. Background Like several other tracks on The Cars, "Just What I Needed" originated as a demo tape recorded by the band in 1977. Ocasek had originally written the song in the basement of the commune he lived in at the time. Cars keyboardist Greg Hawkes recalled the first time he heard the song in an interview, saying, "I remember hearing 'Just What I Needed,' thinking ... 'Wow, that's pretty cool. It's got something sort of unique about it, its, like, nice and consise and ... fairly short pop song format' ... so I still remember hearing that for the first time." The song first appeared in 1977 on Boston radio stations WCOZ and WBCN from the demo tape, along with its future follow-up single "My Best Friend's Girl". DJ Maxanne Sartori, who was given the tapes of these songs by Ocasek, recalled, "I began playing the demos of 'Just What I Needed' and 'My Best Friend's Girl' in March during my weekday slot, from 2 to 6 p.m. Calls poured in with positive comments." Shortly thereafter, it became one of the stations' most requested songs. Composition "Just What I Needed" is a new wave and power pop song, described as having a "hard rock punch". The song's opening riff was borrowed from "Yummy Yummy Yummy" by the Ohio Express. It also features a prominent keyboard riff performed by Greg Hawkes. The lyric "wasting all my time-time" is a reference to "Sister Ray" by the Velvet Underground, a band Ocasek credited as one of his favorites. The song was sung by the Cars' bassist Benjamin Orr, in a performance that Ultimate Classic Rock described as "perfect." In 2003, pop rock band Fountains of Wayne would in turn copy the Cars' take on the riff for their song
