I don't think it's reasonable to include (pop) musicians. Pop music fans, who decide what's a hit, skew young, and are influenced partly by how much the star prancing on stage attracts them as an imaginary sexual partner (or role model). Stardom involves a lot of intuition, charisma, and personality, all things a young person might have by accident. There's also a "voice of the [...] generation" trope that's more plausible if you are one of that generation. So yes, many albums are released by youthful stars and gain attention due to their youthful relevance, sex appeal, and physical fitness (non-rusty voices, nimble fingers, jumping about): and if coincidentally also good music, they're likely to overshadow later albums that are only good music but connect with less visceral urgency to their audience. With, as you say, many exceptions (Wilburys).
