Can't Get This Song Out of My Mind

Our experience in Hungary last fall is like a song that keeps getting stuck in my head, except that I can't listen to the live song again.  Pictures and videos are like listening to recorded versions of the song, and they are great but bittersweet, so I really don't overindulge.  But the song still keeps playing over and over again in my head.  Maybe the inability to have the "real" thing will keep it from becoming the great song that I am sick of because I've heard it to death.

"I'm just trying to find a decent melody
A song that I can sing in my own company...
And you can never get enough
Of what you don't really need now"

U2, "Stuck in a Moment", All That You Can't Leave Behind
