A new music application called MashApp that allows users to create real-time “mashups” of popular music tracks officially launched in the US on Tuesday (February 18). The app, initially available on iOS devices, has secured licensing deals with Universal Music Group, Sony Music Entertainment, Warner Music Group, and Kobalt Music. This means users can access an extensive catalog of popular hits to mix and match. Source: Universal, Warner, and Sony ink licensing deals with new music creation/social app, MashApp
