With iTunes Match-which costs $25 annually-you have access to your complete iTunes music library at any time.

ITunes Match is a service that stores all your music in iCloud-even songs imported from CDs or not purchased in the iTunes Store-and makes it available on up to 10 of your devices and computers. That’s why I use iTunes Match and iCloud, yet also have my music library on an external hard drive connected to my iMac. Call me old school, refer to me as a dinosaur but I don’t trust all my digital data to reside solely in cloud services such as iCloud.
