6. A Real-Life Engineer
Your friend says he masters songs. Your friend is a liar. This is probably the most costly endeavor but it’s worth it to spend a bit of money for your major songs you want to promote. The keen ear can detect a poorly mastered song and you want to get someone who knows what he or she is doing. This can also be done on a few campuses out there. Get some people that are trying to master their engineering crafts to work on your song and they’ll do wonders for you.
