I often heard the story that the best songs happen in just few minutes. Well, in my experience the best ideas may happen in just a happy accident in few seconds. But I came across interesting information from one of the best producers on the planet. It says it took 3 months to make one of his most famous Amiga tracker songs. Since doing that he went to produce some pop music which still gets played every year on the radio despite being 2 decades old now.
I just wanted to put this information out there incase game producers and publisher need to know how much time they need to allocate for music production if they hire a musician - as much as I hate to say this - it doesn't make sense to hire a musician. It's much better to have a person with ability to see what the game looks like and what it should feel like and have that person go through suitable tracks (I'd say if you want 1 great / unforgettable track you need to listen 1000 tracks, and in my experience it takes about 5 seconds per track for fast paced music, up to minute per track for ambient/classical - I'd reserve couple weeks atleast to get 20 good tracks for a game sorted through from unknown material) for the game and then find the person who made the suitable tracks and commission few more tracks. If each good track is assumed to take couple months to produce, well you can figure out a fair price for couple months of work surely if it's exclusive to the production. Personally I am not sure any musician can hope to make such money until they are famous and some maybe not even then. That's why I postponed my career in music production until such time that I can afford it without needing to actually sell or market anything because I like buying and picking more than selling and marketing. Well - unless the product is so good that it'll sell itself, I do occasional free promotion for other peoples products that I see being worth it. One thing I'm looking out for is GSB2. Back when I promoted GSB1 here I didn't even know it had support for mods, not surprising considering the games developer admitting he didn't know about there being mods either despite having built a mod support. I wish he had made more noise about the mods earlier since the biggest complaint about the game was too little value for the money.
