I want my website to be able to convert mp3's to a downloadable ringtone version.
I currently have a developed mp3 store. I want users to have the option to convert mp3s in their store to ringtone format and sell the song as a ringtone.
Customers must be able to listen and access the music from their cell phone. It must also be easy for phone users to buy the ringtone and download it to their phone.
