Apple has released its Cloud Player app for the iPad, some six months after it came out for the iPhone and iPod touch.
Your music. Everywhere. Listen to your music collection from the cloud on your iPhone, iPod Touch, or iPad anywhere you are. You can download or stream your library from the cloud – or play the music you already have on your device.
Amazon has made several moves to expand its cloud music platform in recent months. It has optimized its music store for mobile Safari, made free digital copies of all CDs ever purchased on Amazon.com, and introduced a new "scan and match" service similar to iTunes Match.
