In January we pointed to a possible HP music cloud service that could debut with their future TouchPad tablet due to their 3par acquisition. Such a service had the potential of upsetting Apple's iTunes kingdom. Then word broke in April that Apple was acquiring iCloud followed by news in May that Apple signed a cloud-music licensing agreement with EMI Music and others. Today, a new Apple patent application dating back to Q4 2009 shows that Apple has been working on a cloud based media service for some time. Apple's patent details a very unique approach to cloud based services using iTunes which they describe as being "seamless and invisible to the user."
