God I'm reading through and I've thought of another one.
This thread is apparently therapeutic 
When I left my abusive ex, I was only 21, single mum, hoped I'd done the right thing but found the hardest thing was how much I knew I'd hurt him
he was also threatening suicide which really freaked me out even though I knew it was a power play. I didn't want to be with him, but I didn't want him to be dead!
Anyway there was a song in the charts at the time. "Beat Again" by some crappy boyband. It was fucking awful but because it was "romantic" it was played everywhere at the time and it made me feel so horrifically guilty!
I knew (thanks MN Relationships!) that it was a load of emotionally manipulative horseshit but I couldn't cope with hearing it all the same. These are the lyrics:
==================================
Damn, the doctor's just finished telling me there's no time
Losing you could be the end of me and that I
Should do the things, that I wanna do, how could I?
Without you, without you, ooh, ooh
Cause you're the only one I let in
Tell me how to stop this feeling spreading
I'm hoping somehow that you know, ooh, ohh
Let's just get back together
We should have never broke up
They're telling me
That my heart won't beat again
We should've stayed together
Cause when you left me it stopped
They're telling me
My heart won't beat again
Won't beat again
It's killing me
Hey, hey, hey
If I died, yeah would you come to my funeral
Would you cry?
Would you feel some regret that we didn't try?
Or would you fall apart the same as I, I, I, I
Oh and would it always haunt you baby?
That you missed your chance to save me
Cause you know it's not too late
Hey, hey, hey
====================================
I mean, JFC!
I feel the same about a lot of Bruno Mars' songs as well BTW but at least they weren't saying "Your ex is going to die and it's your fault".
Honourable Bruno Mars creepy song mentions:
Locked out of Heaven, aka "I enjoy sex with you therefore I am entitled to have access to it at all times, you are a frigid bitch for denying me"
Grenade, aka "I make grand meaningless gestures and am pissed off you don't give me whatever I want in return"
Just The Way You Are, aka "Women's only value is in their looks"
Ugh I hate that whiny voiced wanker.
