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.”

Here, Prince seems to hearken back to his electro-funk epics of the 1999 era; but rather than retreading past glories, he does so with a sense of tacit self-one-upsmanship, showing just how far he’d come as a musician and producer in the past two years.

With “Doves” now on deck for his next single, Prince was in the market for a suitably killer B-side–a role “17 Days” would fill with aplomb.
