I think everyone's forgetting the ULTIMATE SONG: BOSTON'S MORE THAN A FEELING!!!
It really depends on my mood though, when i'm "down and out" i'd go with "Burn" by [link=http://www.thecure.com]The Cure[/link] or "Wasted Years" by [link=http://en.wikipedia.org/wiki/Cold_%28band%29]Cold[/link] , and "The Noose" by [link=http://www.aperfectcircle.com/]A Perfect Circle[/link] .
When i'm rockin' out it's all about [link=http://www.lynyrdskynyrd.com/]"Freebird"[/link] and [link=http://www.journeymusic.com/]"Don't Stop Believing"[/link] .
When i'm inquisitive, i go for my IDM/Post-Rock like anything by [link=http://www.explosionsinthesky.com/]Explosions In The Sky[/link] , [link=http://brainwashed.com/godspeed/]Godspeed You! Black Emperor[/link] , an of course A Silver Mt Zion (project of Explosions) and "Come and Play" by [link=http://www.digitonal.com/content/]Digitonal[/link].
There's nothing better than [link=http://www.cursivearmy.com/]Cursive's [/link] concept album "The Ugly Organ", or [link=http://www.mellowdrone.com/]Mellowdrowe[/link] , and the wonderful [link=http://www.elteneleven.com/]El Ten Eleven[/link] (local band).
Electronica needs no other than [link=http://www.autechre.ws/]Autechre[/link] and [link=http://www.royksopp.com/]Royksopp[/link] , mixing would be [link=http://kidkoala.com/page/page15.htm]Kid Koala[/link] .
There's folk too, and mashup, ska..... hmm... i think i need another external for my music... how can i pick just ONE SONG!?!?!?
