Muse Breaks RMX - Infected Mushroom
When I first heard this song, it was on a misty morning, and I was waiting for the bus.  The intro to this song is amazing, and just those soft synth-bells made the strongest feeling of nostalgia come up and overwhelm me.  I felt like I wanted to hang out with old friends, and how I missed that feeling so much...  This song reminded me of that.  According to my fursona, he's had a LOT in his past, and could also relate to wishing he could relive old experiences...
That, and the yell of AAAAAAAAAA that lasted a long time freaked me out when it started raising in pitch.  It was really funny because I thought that it was the guy yelling the whole time.  =3
