Hi Nadia submissions are like junk mail unless they come from a bona fide source. Do you open, read and reply to junk mail? Not many people I know open or read junk mail therefore it is no surprise that the record companies who get hundreds of thousands of unsolicited submissions do not have the time or inclination to listen to them either. There is more than enough great material already in their vaults and even that takes some amount of work separating the wheat from the chaff. The fact that you have even received a "nice no thank you" letter back is a triumph. I would concentrate on making quality demos of your very best songs and finding out WHO exactly to pitch to. Find out who is actually currently in the market for your kind of material. Do your homework and target market. I use this analogy....More chance hitting your target firing a rifle with a telescopic laser sight than letting off a machine gun in the dark when you know there is no one around.... that is just wasting time and costly ammo. Buy the trade magazines and look at the ads as a starting point. Visit the web sites of the people you may want to deal with and find out how to get in touch with them properly. Contact agents and management companies. You need to change how you are going about things so you can be more productive. Even then there is only a slim chance you will be successful but if you want it you cannot give up....TRY HARDER get a thicker skin and be more persistent.
