I think the two PVs and songs are different enough that while yes, they both involve combustion, the things they symbolize are so different that I really don't have anything against Crossroad.
Also, if you're really eager for some real/non-lazy pyrotechnics, don't forget Ayu did do fairyland
Anyway, I'm not gonna stone you for thinking they're similar, but just a heads up, this thread could go down a scary spiral, just based off what i've seen in other threads of a similar nature...
