The song I can relate to the most is "Let Down".
I loved my ex more than anything else in the world and we were together for more than 2 years but then things suddenly started to break down between us. Later on I found out it was another guy, but she just refused to tell me anything at that time. It was much later that I found out it was another guy. She never told me anything directly, instead she behaved in a manner that would make us fight, even trying to make me hate her, so I thought I'd be the one to leave. And the reason she gave for that: she didn't want to hurt me.
And now my current gf behaves in a similar manner. I don't want to lose her so I want to use my previous experience to try to work things out but I don't want to hurt myself again either. So the song totally fits.
Thanks, DBS for making such a song and thanks LPxDC for such a cool contest!
