I went to a Megadeth concert like 5 years ago, and before the band came out, they played random "filler songs" tp pass the time while everyone got settled. One of those songs was "Home". When I heard it I was freaking out. After that song played a guy came out and said "did you guys like that one?" and there was some kids near me that went "Nooooo, booooo" and in my head I was like "well screw you guys, this band is awesome". But yeah...that was my only mainstream experience with Dream Theater.
