This is why I do not accept commission work on new projects. Where as I have to make something that fits with a video game in progress. Instead what I do is create full songs, name and tag them with appropriate moods. And if you want to use anything that I have created I make it extremely easy for anyone to just use it in their work with little or no action required to have the song used in their projects.
There are millions of songs on newgrounds already. Wait maybe not millions but a good hundred thousand to search through to find something that you think would fit your game. But the problem is the amount of time you have to at least LISTEN to what has already been created. Even though the average artists can take upwards of weeks to create 1 four minute song complete with a chorus and a few verses.
Honestly if I was any game developer I would be using the search function found in the audio portal and inputting search words like "sensual moment" or "savage beast theme." The search button could probably get rid of the guess work with having commission work accepted with no substance.
And with so many people who are afraid of failure or rejection it is probably why you can't ever get a commission completed.
Honestly I would love to accept commissions, but I fear that I would become less of an artist, and more of a music machine pumping out another generic tune that might or might not really catch on in the gaming community like undertake.
I make music to share. If it ends up in a video game then cool. If not it doesn't hurt me. Music is one of my many passionate hobbies, not my meal ticket.
I love it when people challenge me in a music one off because it sparks creativity. But I think most of the people here really aren't that adventurous in music production like I am. Maybe there might be some, but not a lot.
However again. Use the search button to find some music. That is what the original purpose of the audio portal was meant for. For people to find sounds to use in their projects. Instead of coming into the forum to find someone to make something specific to the game you are currently creating.
