Totally this one. At first I didn't like this song, but with each subsequent episode and the increasing quality of the anime (it's a shame that it's only technical :F), I got more and more involved. I like the singer's voice, the light atmosphere that fits the songs from the old Bleach series (both in the case of openings and endings). It reminded me that when I was a teenage otaku, I usually waited for full versions of Bleach songs... When was that, but I'm old xD. Good song, brings back memories.
