As part of Amazon’s monthly $5 MP3 Album Deals, Aerosmith’s 1975 breakthrough rocker Toys in the Attic is on sale for only $5. (You can also purchase Toys in the Attic on CD for just $6.88.)

Released in April 1975 by Columbia Records, Toys in the Attic was the Boston band’s third album, and it would soon go on to become the biggest-selling album of their four decade recording career, unless you count their eleven-times-platinum Greatest Hits compilation from 1980. The record spawned two hit singles that would become the band’s most iconic tunes – “Walk This Way,” written by lead singer Steven Tyler and lead guitarist Joe Perry and inspired by a viewing of Mel Brooks’ comedy classic Young Frankenstein, and their whiskey-smooth paean to young lovin’ and hell raisin’ “Sweet Emotion,” penned by Tyler with bassist Tom Hamilton. In a way Toys is the definitive Aerosmith album: each song is a classic rock radio perennial and a brilliant demonstration of the band at the peak of their blues-rock fusion powers.
