We really do think alike; I was also about to say in my previous post that I found the first half of the album (up until Sora) stronger, but then scrapped that part because I was getting too wordy.
But yeah, the second half is not quite as good.
My favourite song is definitely BLUE, I've been listening to it over and over again. It's so catchy and the melody is lovely, it sounds sweet and fresh, it's got all the emotional punch of a good ballad with zero sap...
Nice to hear how the album is charting! I hope it does well.
