This is probably going to be my shortest Song of the Day so far (unfortunately), considering that this next track is less than two minutes long. So here's a little review for Shift (Interlude).
The beginning starts off automatically with a synth as the melody. It's quite repetitive, and continues until a harmony comes in at 0:14. This harmony is a very low synth, and is a nice touch to add for melody support. There's a slight key change at 0:22, and the song continues. The key will soon change once again at 0:27, becoming what it previously was. There is another added synth that comes in though for added effect. Then once again there's another change back to what it was at 0:22. The whole thing seems very repetitive. It goes back again into the previous key at 0:41, although I can tell that the harmony is a little bit louder here. At 0:48, it changes into a different key that hasn't been heard yet, and then changes into yet another key at 0:55. The harmony can also be much clearly heard hear also. At 1:02 I can hear it much easier, and there's another key change also. At 1:09 it goes back into the original key (the one from the very beginning). At 1:15 there's a slight change: the high synth that has been playing has now disappeared, and leaving behind the lower melody, the harmonies, and the bass (each one is a synth). This continues and repeats itself until 1:36, and then the song is already over.
Pros: I would say the pros would have to be the different key changes. They keep the song interesting, and each one seems to work with the song.
Cons: It's too repetitive, and again it needs more. I couldn't really tell what the melody was, and it was pretty much the same thing over and over throughout the whole song. Plus the ending could have been better also.
Overall: There really isn't much to say about this song other than it needs more work on it. Sorry for such a short post today.
