what does this get you? This usually gets you laid. Here's the secret a lot of the songwriters I've met living here in Nashville talk about using when they were younger:
What you do is you write one really good, really pretty love song. Not some peice of AFC garbage that is just fluff lyrics you came up with as you got the melody, but some good lyric writing that you have seriously edited and re-wrote until it was great. Really pretty melody and the whole thing.
Then, you never let anyone hear the song unless it's a girl you're dating and you're ready to really impress her. You tell her that you wrote the song for her recently, and then you play it.
What makes it great is you can play the same song for dozens of women, so long as none of these girls ever make you play the song publicly.
You don't realize how many points you'll get for writing a song for a girl. Here's an example:
So a while back I'm dating this girl. She breaks up with me. The first thing I do is sit down and spend twenty minutes writing a pissed off break up song. The verses were all the ways in which she sucks, and the chorus is about how she can **** herself. I wrote it really quick, then went out with my friends and got drunk. It ended up being a pretty funny song, so I'd play it for my friends from time to time as a joke.
A few months later she invited me over and we were having a few drinks and she asked me to play her the song. Even though the song is nothing but insults to her, she still pretty much loved it. She was obviously really flattered that someone had written a song about her. It didn't even matter that the song was all about how she sucks.
Just keep in mind, though, that writing girls songs loses it's punch pretty quick if you're writing her lots of tunes. So don't make it a regular thing.
