for the person who asked if anybody still listens to Pearl Jam, yes there are millions of us - they've maintained a large loyal fan base despite very limited promotional activity (by their choice). they still sell out large arenas and stadiums around the world, and are about to put out their 9th studio album.
in fact, i made it a point to reply because about 60-70% of my running Ipod is filled with Pearl Jam songs. off the new record, the songs "Got Some" and "Supersonic" are outstanding for running. "Got Some" carried me to a personal best in a 4Miler just yesterday. Great tempo, great lyrics. Other Pearl Jam songs that should be on any Rock fan's running playlist (whether you're a PJ fan or not):
Lukin, Corduroy, Go, Blood, Given to Fly, Save You, Life Wasted, Do the Evolution, Last Exit. Of course, old standbys like Alive, Once, and Even Flow are great too.
Aside from Pearl Jam, I also like Eminem, Alice in Chains, Nirvana, Beastie Boys, Metallica, The Who, Rolling Stones, basically any hard rocking up tempo rock or hip hop. Thanks to all of you for your great suggestions too.
