This always resonates with me.

ME TOO! I first heard it in Fantasia in the part where the goldfish were swimming around...I liked how the music of this piece is VERY interwoven together and subtle; but everything that comes seems to make sense.
Now, I dunno if this is completely INFJ, but this one song by Lacuna coil seems to capture my desire to live in my imaginary world, and it represents the moment I realized that living solely within it and refusing to acknowledge the outside world was stunting my growth...

I also can't describe it...but I feel like lots of Trip-hop songs seem to relate to me on an INFJ level. Maybe because they're very layered and often deal with interpersonal relationships?
http://www.youtube.com/watch?v=eYTem2DhNak "Hear Me Out" by Frou Frou: this song seems to appeal to me a lot...
http://www.youtube.com/watch?v=ULxCFM4XB_E "False Alarm" by KT Tunstall: I can totally relate to this, and I almost cry every time I hear it... It's like this nagging feeling or idea that I really believe, yet have to suppress it and fake a smile because I worry about the well-being of those around me and don't want to offend them. The very last line seems to remind me of a mixture of the Demonic Si and Trickster Te leaking out at the same time as a last effort to try and wrest control of the situation...
http://www.youtube.com/watch?v=p0SYe5X-onk "They" by Jem: Maybe this is a little more of an INFP song, but I still relate to it coz I'm right on the cusp. The overarching theme of being subconsciously bossed around by society seems very Fi (professing one's morals and being true to oneself) and spotting the connection in the first place seems Ne. However, it doesn't just seem like a song of complaint, but rather a song of empathy towards the masses, a conversational complaint to friends about the silly aspects of the world; such compassion seems very Fe, while the Ni would be largely responsible for the feeling and idea that something is "wrong" with the world.
Well...that's my two cents...and three dimes and a nickel. ^^;;
