Classic rock is about heavy hooks, power chords, and tight harmonies, but it's also about letting loose and enjoying the good times -- and there's no better time than Friday evening, when we pick up our paycheck, punch out of work, and enjoy a couple days of much-needed rest and relaxation.

This Friday, we're paying tribute to a song that perfectly captures that spirit, 'More Than a Feeling,' the leadoff single from Boston's 1976 self-titled debut album. Reportedly penned by bandleader Tom Scholz as a paean to "the thrill one gets while driving fast cars," it perfectly captures the feeling of bright anticipation and soaring optimism that arrives alongside a moment you've been waiting for -- like, say, the end of the work week.

In vocalist Brad Delp, Scholz found the perfect final ingredient to put his songs over the top, and Delp's performance on 'More Than a Feeling' thoroughly encapsulates why they were such a terrific match -- his crystalline tenor lacked the grit of a more stereotypical rock singer, but its pure tone blended seamlessly with Scholz's immaculate guitars, and the combination made for a flawless soundtrack to a Friday evening.

Listeners clearly agreed, sending the song all the way to No. 5 on the Billboard Hot 100 and kicking off a wildly successful period for Scholz and crew. 'Boston' would grow into one of the decade's top-selling albums and 'More Than a Feeling' became the band's defining hit -- not to mention an enduring anthem that came in at No. 28 on our list of the Top 100 Classic Rock Songs. We've embedded the song below, so turn it up, pour yourself a frosted mug of your favorite cold beverage and imagine you're behind the wheel of a '76 Camaro, because the weekend starts now.
