But don't you find it at least a bit interesting or curious that Randy Newman had only 1 hit? When you start separating the more famous artists from the not so famous where do you draw the line about who should be included together and who shouldn't? Then it comes down to opinion or sentiment. You could have all kinds of differing opinions. I just go by the numbers/Billboard charts.
The Music Explosion - #2 in 1967 (#1 on Record World) had one other record on the Billboard Hot 100 which peaked at #63; three later releases "bubbled under"
Springfield had 16 Top 40 hits. No...16 is wrong. I guess he had over 20! A bunch anyway. I had no idea it was that many.
A timely one - lots of charting country singles, including many number ones, but only one Top 40 entry (#22 in 1980.) RIP Mickey...
Jewel Akens - #3 on Billboard in 1965 (#2 in CashBox and Record World) the soundalike follow-up 'Georgie Porgie' peaked at #68
Not sure how high this reached, but one source describes it as a "modest national hit" - Crystal Mansion, The Thought of Loving You:
The Exciters - #4 in early 1963 should not have been one hit wonders - their great follow-up 'He's Got the Power' inexplicably peaked at #57, and their original 'Do-Wah-Diddy' only reached #78 (#1 for Manfred Mann a few months later with the addition of an extra "Diddy" to the title)
Ernie K-Doe - #1 in 1961 The follow-up 'Te-Ta-Te-Ta-Ta' peaked at #53. His later single 'I Cried My Last Tear' b/w 'A Certain Girl' had two great sides, but these appeared no higher on the Billboard Hot 100 than #69 and #71 respectively.
Another who should have had more than just the one hit - Sanford Clark - #7 in 1956 The follow-up 'The Cheat' peaked at #74; '9 Lb Hammer' appeared on the CashBox chart at #48 for one week
The Murmaids - #3 in early 1964 David Gates' song produced by Kim Fowley The follow-up 'Heartbreak Ahead' only bubbled under at #116
The Bobbettes - #6 in 1957 (#1 r&b) They recorded a sequel 'I Shot Mr. Lee' in 1958, but Atlantic Records declined to release this until 1960 when a re-recorded version on the Triple-X label had been issued and began to sell (but peaked at #52). Later releases peaked at #66, #95, #120, and #72. They deserved to have had more big hits ...
The Cascades' Rhythm of the Rain - UK No 5 in 1963. Their very good follow-up, The Last Leaf, did nothing over here, and nor did the Rhythm of the Rain LP (which is several grades above the average "hit plus fillers" collection).
Jody Reynolds - #5 in 1958 The follow-up 'Fire of Love' peaked at #66 (the song lived on by way of later versions including the Gun Club and the MC5)
The Rivieras - #5 in 1964 The follow-ups peaked at #93; #99; and #96 Not the first or the last to record the song Cover versions of California Sun written by Henry Glover, Morris Levy | SecondHandSongs
A “quality deep cut” is not a hit. It is not universally define-able, nor identifiable. A hit is. Once you define the rule (chart and minimum chart position) then all songs either meet or don’t meet the standard. Of course that takes away “our” power to decide who “we” think should be considered one-hit artists. Some don’t like that which I understand but find moderately amusing
