I don't recommend Soundbetter,'
Try finding another way!
This is one example of how SoundBetter breeds corruption:
The site is filled with vocalists. They use your ideas and song to pad their own brand (the don't care about your music, they are just using you). Don't believe me? Ask them, they will never sing your songs live or anywhere on the internet. They will lead you on till they bleed your dry and then ghost you. Steer clear of Soundbetter if you are sincere about succeeding in music. Sadly enough the music industry is predatory. I hope this saves someone some cash, sanity and time.
