I'm waking up, I feel it in my bones
Enough to make my sisters moan

The story:

Okay so this one wasn't me, despite my penchant for
mishearing lyrics. This one was a good friend of mine. We
were carpooling to a get-together and this song came on
the radio when she started to sing along and the first time it
didn't register that she sang what she did but the second
time I just stopped her and I was like "Wait, hold on. Sing
that again" [She sings] "Those are not the lyrics. It's 'Systems
blow'." and she frankly was just glad that the real lyrics are
not what she thought they were.
