Peggy, I feel your pain. Had a major artist supposedly going to hear one of my songs, even got some of my songs to Scott Borchetta in the begining of the summer, handed to him personally by one of his good friends. And all I heard back was crickets. I got nothin'! But I wasn't suprised. And I didn't even ask to have it done..it was a friend of a friend trying to do me a favor. I didn't even really want to do it, because I'm not 'there yet' but it was one of those opportunites I couldn't pass up.
Hey...for what it's worth I hope that he does respond to you! You never know. I'm still an aspiring songwriter and I don't claim to know much, but one thing I already do know is - you can't get too excited about anything!! LOL. Seriously, it's such a rollercoaster of emotions and you can't hold your breath for one of these people to come through for you. Just like songs you write...you can't get too hung up on any of them. I try to write them as best as I can and then when they are done...NEXT!
I think the bonus to getting out of your living room like MAB says, writing with other people and things like that, is at least you're having fun in the process and meeting new people, making new friends and forming relationships. Stay busy and forget about who you've submitted your songs too, or whatever the case is. Then, maybe one day you will be geniunely (and pleasantly!) surprised!
