MP3 Download Pro is an Android app that, like much technology, can be used for lawful as well as lawful purposes. The Recording Industry Association of America wants Google to block access to the app because some, perhaps many, consumers use it to download copyrighted music onto their phones. So far, Google has refused to comply, on the ground that the app has lawful uses (such as downloading music that is in the public domain or that has been made available by the copyright owner). The RIAA can easily intimidate individual consumers but in Google it has likely met its match.
