Whenever I hear The Beatles, Rod Stewart, David Bowie, Queen, Journey, Def Leppard, Leo Sayer, Cliff Richard, Kate Bush, The Police, Sting, Rupert Holmes, Robert Palmer, Hall & Oates, The J. Geils Band, Phil Collins, Pet Shop Boys, Tears For Fears, Billy Idol, Adam Ant, ABBA, Air Supply.
Alot of classic rock songs will make my mind flash around even though they were before time because they were played constantly growing up.
No Rain by Blind Melon however was during my time so I'll list that one and so was Metallica Enter Sandman and Time of your Life by Green Day, Falling into Sleep by Mudvayne, Black Hole Sun by Soundgarden, as well as War Pigs by Cake... The list goes on and on. Lots of music played all the time. Mind you feelings of Nostalgia isn't always a good thing.
