I like the idea a lot! The melody at :22 seemed really out of place when it first came in. I think you needed a clearer transition when it first came in. Other than that, you mesh all these tracks (many of which I love, btw) together quite well. I liked the instruments throughout. One tiny thing that bothered me is that the brass synth pad at 2:30 was a little too loud IMO. There were some other minor balance issues too, for example the drowned-out melody at 2:50. Other than that, I love all the synths, and you kept up the intensity and mood throughout. The ending felt a bit inconclusive, but I imagine it was hard to end it given all the various songs you crammed in here! Love the idea, and it helps that I'm familiar with about half of these songs. :) Keep up the good work, LunacyEcho! ;D
