By NICOLE LEE — ENGAGET–Right now if you want to upload your stash of tunes to Google Play Music, you have to download Music Manager, an application that hooks into your computer’s hard drive so that you can transfer selected audio files to Mountain View’s storage cloud.
But what if you don’t want to download yet another piece of software on your already bursting hard drive, or you just want to upload a few songs from a friend’s computer without having to get the app?
Well, according to an eagle-eyed tipster of the unofficial Google system blog, you might be able to upload songs directly from the browser in the not-too-distant future.
