By "classic rock", I mean the typical "idols" and well-known artists of pre-90's music, such as Led Zeppelin, The Who, Jimi Hendrix, etc. It's not that I don't enjoy them. I just don't go out of my way to listen to them. I used to love all of them, but that was only a musical "phase" for me.
My frequent plays are (but not limited to) Bright Eyes, the pAper chAse, St. Vincent, Xiu Xiu, Cursive, The Octopus Project, The Deceraberists, Fair to Midland, Porcupine Tree, and much music that makes up the Denton, Texas, music scene.
As for Nirvana, they were the only grunge band I ever got into. Alice in Chains and Pearl Jam only mildly interested me.
And the Trapt thing was me grabbing at what I used to listen to. I still think it's a good album, and would listen to it all the way through, but not more so than once every few months, probably. It just doesn't come to mind that often.
