I actually got asked to do it once, but declined. There are many ways to become a paid songwritter, but you have to go through the same stuff, if you had a band. The best way to get noticed is by entering a songwritting contest and place. There's plenty of those on the internet, and some are actually judged by people who work in the music biz and are looking for tunes. Those will cost a fee (unless 20 a song) but if your tune is good enough, it's what you got to do to get there. Who knows after that, if you become a consisted writer and someone notices you, well you might be able to make a living off it. One contest that goes yearly pays 50 grand to the winner. Then again the winners usually write pop songs, that you might see B.B mack play. You have to write what is popular to do it that way, in my opinion. The acts that buy tunes are usually country, and pop acts, very few rock acts unless it's corporate rock. That doesn't sit well with the public though. Another way to make a buck as a songwriter is, from movie producers looking for tunes for there movie. You can make a hefty buck if your tune gets in a popular movie. I believe Evanescense (sp) made a huge dollar and plus got signed by a major label, just for being in the movie spiderman (i think it was spiderman or maybe daredevil). There's alot more freedom in writting for movies than for corporate acts. I'd like to write tunes for horror movies myself.
