Prince's pop life, song by song, in chronological order.

While “Glamorous” sounded tailor-made for Sheila’s particular talents (even if it wasn’t), “Belle” is well-crafted but faceless, embodying the essentialist cynicism of the publishing imprint Prince used for his female side projects: “Girlsongs.”
“Close and Slow” owes as much of its ambience to folk-infused 1970s soft rock as to any kind of R&B; in particular, it’s another early signal of Prince’s artistic debt to Joni Mitchell.
Prince’s one-man jams were, at least in part, about showing off. And on his second album, “Sexy Dancer” was the designated show-off track: a loose four-minute jam that gave Prince the drummer, guitarist, bassist, and (especially) keyboard player their respective shots at the spotlight.
In hindsight, “Why You Wanna Treat Me So Bad?” sounds like pop/rock perfection; but, like many of Prince’s early “rock” songs, its unique blend of genres was ever so slightly ahead of its time.
