I'm not sure... they really seem to exaggerate the "love song" nature of it. If it weren't for that, I'd think mid-tempo. Let's see what the BBS has to say... -checks-
Okay, looking at comments:
- Last Links could fit in with End of the World or Heartplace from PCDL
- Dark orchestral melodies in Don't look back are present in montage[?]
- Jump! has some layered Ayu digital electro rock vocals with Ayu saying JUMP a bunch of times it seems? A lot of people like it.
- THE introduction has a feeling of a "LIVE CONCERT OPENING" or something
- People really like her vocals in meaning of Love and say it's a ballad with a strange/pretty melody
