For anyone who's already screaming "Enough!" whenever Avril Lavigne's supernaturally catchy single "Complicated" comes on the radio, the news is all bad. Let Go, the debut album from Ontario's tiny terror, comes fully loaded with another dozen infectious hymns of Total Request angst. Although it's the only track with a definable style other than "pop rock," "Sk8er Boi" is seventeen-year-old Lavigne's signature moment. Over a rush of nouveau-punk guitar chords, she narrates a funny story line (preppy ho disses young scofflaw, who then becomes MTV star and — psych! — Avril's boyfriend!), but none of it would matter if Lavigne didn't have a voice, equal parts baby girl and husky siren, that seems capable of setting off car alarms several city blocks away. "Mobile" should be her next completely inescapable hit: As Lavigne wails over crashing waves of acoustic and electric guitars, her big voice occasionally turns sideways in a drawl, a casual hint that she may actually be, of all things, a fine country singer in the making. Truth be told, Lavigne has a great voice, a good shtick and a qualified staff of hitmakers. We should all just learn to get along with her, because she's gonna be with us for a little while.

“Everyday People”

"Everyday People" managed to trailblaze in two different ways -- it was one of the first pop hits to deal with the subject of racial harmony, and it utilized Larry Graham's "slap" technique on the bass guitar, which would soon be copied by countless other bassists. Graham once said about his pulsating style, "I'd never done that before … that's where the freedom of creativity came in for the band, that we'd be allowed to do that." In 1978, the song's line "Different strokes for different folks" would be borrowed for the title of the hit television show Diff'rent Strokes.
