nearly time to call mercy :D

LSR definitely.I find LSR's opening to be a rather good song. RPM however.

I'm going to go for the song that has more than three lines of lyrics.

RPM's theme is not the best. However, it is much more lively than Lightspeed Rescue's theme.

Onore, Sentai!
You pit the amazing triumph-chimes of PRLS vs the awesome rusty-grunge of RPM!
I cannot choose!

Okay, I can, I pick Lightspeed Rescue. Because of that deep brass chiming in the beginning riff. I like it because it just sounds awesome.
But I will STILL love the RPM theme.

I'm calling this on the behalf of Mercy. I don't see RPM mounting a miracle comback, so onward to the Final Four!
