I prefer they're type of songs more.. i dunno.. its more classy..? i love Epsilon Phi because Shu's Seiyuu makes anything sound good (seriosuly though.. he made a song called Patatoe sound excellent..)

But with Fantome Iris i LOVE they're songs... and.. my favourite Argonavis song (out of the whole lot of bands of Argonavis not the band Argonavis..) is Rhapsodia... 'v'

(I do love Play With You.. but still not as much as Rhapsodia..)
