Dear Yuno,
liftedCREATION takes 1 to 3 days, up to a couple of weeks to complete our royalty free production tracks, this is determined by the music production track length and amount of full orchestrated instruments we are going to include in our production mix. We take our music tracks to all different types of audio devices, home stereos, cars, ipods, etc. There is a period of intensive listening where we try to hear our music on as many different formats as possible so we know what the track sounds good on, this is a good technique whenever you are going to produce music. We then mix our production tracks accordingly.
It is all in how complex the production track is. Simple beats and loops are generally produced in a day but take a week or so to get right. Full Orchestrated tracks may take many weeks to perfect and get right.
Don't be shy to take time in your production music. Quality over quantity...
