The Primitives: Lovely (1988)
Lead singer Tracy Tracy matches the joyous guitar-driven power pop with her infectious, girlish but sturdy vocals, digging the hooks deep. The album wisely leads off with "Crash," one of the finest pop songs of the era, the sort of thing that begs to open up all your mixtapes; but another half dozen songs are every bit as perfect, delightful ear candy that sticks in your head. "Through The Flowers" and "Spacehead" add some of that buzzing ambience to sugary sweet pop tunes; "Way Behind Me" (a later single added to some pressings of the album) has a classic Motown-ish vibe; "Nothing Left" and "Out Of Reach" similarly milk tons of fun out of just a few chords.
The whole thing is a pretty flawless pop gem, still fun after all these years (and the follow-up, 1989's Pure, managed to draw more magic from the same well). After one more album, the perfectly solid Galore, the band broke up, but returned in 2012 with Echoes and Rhymes, which adds a few new tricks and updates the sound but otherwise picks up right where they left off. All are guaranteed to improve your mood no matter what.
BTW, back around '90 I saw them play in Chicago, opening for the Sugarcubes. The Sugarcubes were good enough (hey, it's Bjork, of course they're going to be entertaining), but the Primitives were definitely the better gig that evening.
