What does this say?

Mmm... can anyone help me read this? O.o It's so small and bled so much that I can't read the first kanji in the second line!!!! :x



The 2nd/3rd/4th kanji are:　筋　背　筋.
But what is the first one??? Any idea? It's from a song, but I don't have a copy of the whole song to hear the lyrics. (Long story)
