Beaky...
After following the links to trackspin.com I just listened to your songs....thanks for posting. If I'm being honest I felt alot of heart in your recordings but in no way are they ready for commercial use or for sale at this time. I dont know if the others are just being nice but you did ask for opinions of being a song writer....the music is seriously Yamaha style arrangeresque but not too bad....but the singing needs much improvement, phrasing & your all over the place in pitch if you listen close. Levels need attention also.
But dont let this ruin your dream....just make it a stepping stone to bigger & better things....I'm sorry for being so blunt...but I feel if I dont say anything like many here try to sugar coat nothing can be improved upon dont you think? Good luck in your songwriting career.
