If I can find a link I'll share, but my favorite music in anime is the music from FMA.  This is because it they made it fit so well and it blends flawlessly. When songs can blend seamlessly, you know you did your job well.

  The video is Brothers from the 2003 FMA, preformed by Taylor Davis, If you like it I realy do suggest subscribeing to her, she is a great musician!
