Like vitamins hawked on late-night TV, the entries on Little Hits are easy to swallow and really do reverse the aging process. The setup is as simple as any MP3 blog: song for streaming plus quasi-literary reflection on song. Most such sites worship the new and the cool, posting buzzworthy leaked singles from the latest Brooklyn it-bands. Little Hits lives, lounges and inhales the record-store air of pop music's past. For nearly three years, the hits have been coming regularly, building up a vault of lost ditties from as far back as the '50s and as recently as the '90s — a decade that Little Hits seemed to have spent in a parallel universe. Just listen to the '60s-via-R.E.M. jangle of "She Understands" by the Summer Suns from 1995 or 1990's "Shower Curtain" by the Ant Farmers, a song in which a guy named, oddly, Carl Peterson, placidly croons, Somehow you convinced yourself your girlfriend fucked the shower curtain up. The site's founder is Jon Harrison, former used-record buyer for Love Garden, but this year, a cat named Stewart Mason has taken Little Hits into 2.0 land, with a new look that complements the thoughtful prose and downloadable MP3s. Go for the natural high of a Little Hit each working day.
