I used to be so crazy about Once Again back in the day but I pretty much overplayed the song so today I find it a little bit boring. I love the fact that she experimented with reggae with it though. I was getting into the genre that year so Once Again was very popular in my playlist.
It does have that lovely summery feeling though, and those lyrics are very positive. Kuu's voice really fits nicely together with this song too.
I'm listening to LIVE TOUR 2005 ~first things~ mp3 rip right now. I love this concert so much. I remember when I watched it with one of my friends and she didn't really appreciate it that much. I was personally like, "omfg, yey \o/" the whole 2 hours haha.
