2 and 7?

2: Haemoglobin by Placebo

At the time they cut me free
I was brimming with defiance
Doctors looking down on me
Breaking every law of science
[...]
I'll go fighting nail and teeth
You've never seen such perseverance
Gonna make you scared of me
'cause haemoglobin is the key

7: Man I'm gonna have to give that one some thought 🤔 Which song have I most aggressively misinterpreted?

Probably The Kill by 30 Seconds To Mars, which is almost definitely supposed to be about a bad relationship
