Anyway, the words filtered through my headphones enough to make me realize, wait a minute...these are japanese words I'm hearing. So I listened and thought they're pretty good. Then, as is the natural progression of how these things are done, I went on the net and googled them and was pretty pleased that they're indeed j-rockers and not a k-band belting out their japanese release.
They've been around for quite sometime, although I haven't got to finding out whether the band still has the same members or they've been playing that musical chair sorta thing like all the other jrock bands I've liked previously (i.e. disbanding > forming new bands > shuffling members around as they pleased. I mean, look at the updates in this blog today...this band and that band are disbanding, what even *facepalm*).
Here they are: SPYAIR with a theme song from an episode of Bleach, my (only) favourite shonen manga~
