Sure there are ways to figure it out but if others have tried before there is likely to be a tried and tested method to find out about. I don't see the harm in asking.
i'm always amazed at peoples inability to just figure this one out. especially now that everyone's got an ipod and a car with an aux input.
I knew how to do this shit when i was 9, i recorded my pokemon games
i have a nother tip: if it is the first song you have ever made, maybe you don't really need to record it
I think you should record as often as you can for the practice of knowing how to record when you finally have something you want to share with everyone. It starts when you arm the track and press record.
You don't have to share all your recordings with the world, and in principle you shouldn't... but ultimately you're going to do what you want anyway.
Good luck, OP.
