Yeah it really gets you in the mood for the show, some of the songs are hard to spot within the actual episodes, the companions for the seasons are good cos they give you a tracklisting for each episode, I love Asia Heat of The Moment,, the music from the show has got me to buy many albums since Ive heard them within the show, Like Creedence Clearwater Rivalvals Greatest Hits (One of my fav CDs of all time) ive also bought ACDC Back In Black, Lynyrd Skynyrds Greatest Hits, Bostons Greatest Hits, Blue Oyster Cult GH, Bad Companies Anthology and a few others, I was never that big of a fan of that genre of Music till Supernatural and Sopranos, both shows have a fantastic collection of Rock, another one I love is Journeys Greatest Hits, to me the Music is one of the main stars of the show, Who can forget the Season 3 Intro with ACDC Hells Bells playing, When Sammy gets stabbed and Dean Shouts his name with that music playing, just typing it gives me goosebumps, or of course Carry On My Wayward Son for the Season 2 Intro, and ACDC You Shook Me All Night for the new season intro, LONG LIVE ROCK! I certainly wouldnt mind listening to Deans "Tapes" while travelling the country lol
