Ok so although I know nothing abut designing a phone app I thought it would be cool if eventually Wikiloops had their own. People are already creating music apps, even ones that you can make beats, upload samples, play synths, multitrack recording, equalizers, samplers, sequencers, etc. Users could download the free version that allows them to view and listen to other users songs but wouldn't be able to download them unless they purchased the full version. Believe me people will pay to play. Also it would be cool to have a thread that included the shout outs and current events. The key is to allow one to create backing tracks while on the go. It would also attract a ton of more users from all over the globe. Feel free to offer more suggestions.
