For me it goes like this:

01. Distance - My favorite song, lyrically, from Hikki ever! It's amazing! Plus I love the original version, the m-flo remix and FINAL DISTANCE too!
02. HEART STATION - Good song, love the beats. Really fun to sing along to.
03. BLUE - I really love the song lyrics... so deep.
04. First Love - Good song, I tend to forget about it a lot though!
05. DEEP RIVER - Umm, it's just okay for me. It kind of makes me fall asleep though.
