"Girl You Have No Faith In Medicine" by the White Stripes. It's the exception to the rule with this list. It's the fuzzy, bluesy, looped guitar licks that get me feeling kinda psychedelic.
"Drive" by Incubus. They have put out more mellow, trippy music (Morning View) and much rougher, crazier music (A Crow Left of the Murder), but this song is the one that stops me, begs me to sing along. I really love the lyric: "Would you choose water over wine/Hold the wheel and drive"
"Bad Education" by Tilly and the Wall. Flamenco-style tap dancing, folk song harmonies and brass instrument loops. It really stands out from the crowd of other songs on my "favorites/decade" list.
"Banana Pancakes" by Jack Johnson. It takes me all of 30 seconds to picture a King-sized bed with a giant comforter on top, big pillows all over the head of the bed, a gentle, tropical rain and Jack Johnson bringing banana pancakes with piping hot Kona coffee to me whilst I lie in bed. What Jack does from there is best left to your imagination . . .
"The Sound of Settling" and "Soul Meets Body" by Death Cab for Cutie. This decade has been really great for this band and their unique blend of high-polish production and mellow, hippie style music.
"Do You Realize" by The Flaming Lips. I'll even add their movie "Christmas on Mars" to this list. Between these two contributions to our cultural society, Wayne and the boys really cannot top themselves. I still well up with tears trying to sing along and this past week's second screening of the movie made me fall in love with that movie even harder.
"Wild At Heart" by Gloriana. Best of the bunch as far as production goes - very slick sounding pop with country flairing. The vocal band is at its best when all four harmonize -- I can't help but evoke The Mamas and The Papas when I hear that harmony.
Try watching this video and I defy you not to tap your toes, slap your hands on something or otherwise groove along with this song.
