MacGuyver.....TRIBUTE by TENACIOUS D?? Wha...? The rest of your list is pretty good, though.
I Will - Beatles (she will fall apart)
Brown Eyed Girl by Van Morrison and Closer To Fine by Indigo Girls - these songs define the term "chick magnet." I used to play them in the dorm and time how long it took for a girl to walk in.
St. Patrick's Day by John Mayer
Daughters by John Mayer
And now, here's a list of songs beginning with "W" that all happen to rock wimmen's worlds. (I didn't mean for it to be all W's, it just happened that way.)
Wonderful Tonight - Eric Clapton
What A Good Boy - Barenaked Ladies (a little sad, but a pretty song)
Walk On The Ocean - Toad The Wet Sprocket
Wildflowers - Tom Petty
I'm sure more will come to me...
