With iTunes Match, all your music — even songs you’ve imported from CDs — can be stored in iCloud. So you can access your music from all your devices and listen to your entire library, wherever you are.

Here is the Google's post about the same feature on Google Play Store.
On November 13, we're bringing music on Google Play to Europe. Those of you in the U.K, France, Germany, Italy and Spain will be able to purchase music from the Google Play store and add up to 20,000 songs—for free—from your existing collection to the cloud for streaming to your Android devices or web browser. We’re also launching our new matching feature to streamline the process of uploading your personal music to Google Play. We’ll scan your music collection and any song we match against the Google Play catalog will be automatically added to your online library without needing to upload it, saving you time. This will be available in Europe at launch on November 13 and is coming to the U.S. soon after. This will all be for free—free storage of your music, free matching, free syncing across your devices and free listening.
