The recent trend toward cloud music has several benefits. Putting your music in “the cloud” can ease synching music across many devices, provide backup in case of computer disaster, offer social tools to share your musical tastes, introduce you to new music, and allow you to stream music on devices that do not have enough memory space to hold a large music collection. Most cloud services do not offer all these benefits, but there is a large selection of both free and inexpensive cloud offerings to choose from. And no one says you have to choose just one. Sometimes the best solution involves two or three different music cloud services.
