Great Anime, Great Song!
I LOVE 'Only My Railgun' its a brilliant OP for the anime, i listen to the song over and over and i can't get enough of it! and the limited edition came with a DVD as well that has fripSide PV to the song and extra's from the making of the PV.

if you can get you hands on the Limited Edition ver grab it! but regardless, get this single!!

A must get
Good OP choice by the creators of Railgun. This is the OP of the series from Episodes 1 to 14. A good listen and a must get.

It also comes with Late in Autumn, which is also more catchy.

Great OST!
I feel like i can listen to Only my railgun for the whole day. The song is just simply awesome.

Only my pick
Only my railgun is brilliant.
late in autumn is good too.
For me, this is the best anime op song in this year.
Well worth getting

only my railgun
