Amazon and Google were first out the gate with cloud music players, but Apple seeks to outdo the competition Monday when it unveils its iCloud music player. Steve Jobs, who is on medical leave, will unveil the online music storage service himself. Unlike Amazon and Google’s products, which require the player to upload his or her music, Apple has worked out deals with the major record labels so that users can listen to music without manually uploading or transferring songs. The iCloud player will simply scan a user’s existing library and then provide access to those songs from any computer. Apple is still trying to work out deals with film and television studios to make their products compatible with the cloud.
