Rearviewmirror - Pearl Jam
Feeling So Real - Moby
Neither of these are my "favorite" songs, but they both had very profound effects on my life. These are both songs you have to *feel* to appreciate, Rearviewmirror being particularly powerful when youa re feeling a bit angsty or down, and Feeling So Real having the exceptional abilty to lift ones spirits. I suggest that your first listen to feeling so real be done with your eyes closed, with the volume at high level and the bass turned up.
Oh yeah, if you want to give Feeling So Real a listen, make sure you get the album version (from "Everything is Wrong) because moby had a tendency of remixing all of his earlier work 435645 times. Say what you will about him now, but "Everything Is Wrong" continues to be one of the most relevant and exceptionally produced electronic albums of all time.
