From Songtrust:
Submit your Songs into Songwriting Competitions:
Yes, there are scams out there, but don’t let that stop you. Many songwriting competitions can help your songs gain exposure to top music industry executives. They can also help you meet other writers which may lead to potential new collaboration opportunities. The International Songwriting Competition has a panel of judges ranging from Grammy-Winning artists and songwriters to CEOs of major record companies. We also recommend Song Of The Year, The U.S.A Songwriting Competition, and The Great American Song Contest.
Schedule a Co-Writing Session:
Working with others may sound daunting, but collaborating with other writers can sometimes be the best way to come up with fresh ideas you wouldn’t have thought of otherwise. Not only could your co-written songs end up better, but the more people you collaborate with, the more people will be actively playing and advocating for your songs. Don’t be scared to reach out to well established artists and songwriters about co-writing sessions – It never hurts to ask! Always remember that 1% of something is better than 100% of nothing.
Join a Writer’s Round or Open Mic Night:
Writer’s rounds are great places to network with other writers and try out your songs in front of a crowd. If you have stage fright, performing at these places can also give you invaluable experience playing in front of people. Artists like Michelle Branch and Ian Axel (of A Great Big World) started at New York Songwriters Circle, a monthly songwriter’s circle at The Bitter End in NYC. Open mic nights are everywhere and also great places to get exposure to new people.
