MP3.to came from my obsession at the time to make a different site for each format. I had started trying to see if I could get all the "Domain hacks" for these formats. MP3.to and MP4.to both came around the same time as both where for sale around the same price. So they got made. They of course started off as simple little projects, but they got more complicated. Regardless, that is how this little web app came to exist. That now has an API, and a lot more functions. Also, maybe do some jumping jacks. I mean come on, no one cares if you stay healthy. But you should care.
