The Music Manager desktop program for managing uploads from Google Play Music now works with the new version 4.5. Opening the program shows the usual message, Music Manager isn't available. However, any Google Play Music subscribers that have successfully migrated to YouTube Music should do so immediately. It's part of the upgrade to the latest operating system. Music Manager's functionality hasn't been changed - the upgrade simplifies the whole process.
Music Manager for Google Play Music is part of a long line of products from Google that are getting an upgrade. It's part of the company's efforts to become more integrated with its digital product offerings - everything from Chrome, Gmail, and Android. While it's true that most people will never use all the features that Google has introduced in those areas (such as Chrome's "Bookmarks" function or Gmail's new feature that lets you look up your old emails), the new music manager still has some value. If you're a music lover who wants to manage all of your music library on a central interface that you can access from anywhere, it may be worth checking out this software. The interface is relatively easy to use, and you can also access all of your other apps from your laptop if you have one. It's certainly more convenient than digging through your PDA or cell phone for your download sources.
One nice aspect of the upgrade to Google Play Music is the ability to shut it down and turn it into a "stand-alone" app. For those who aren't so tech savvy, this makes sense because shutting it down can be risky if you aren't dealing with an official Google account. If you were to download all of your Google Play Music uploads and shut it down, you could cause serious damage to Google's servers - and Google doesn't recommend this. With a stand-alone Google Play Music app, you can safely download your music library and transfer them into an external flash drive or CD just as you would any other files you'd transfer from your computer to your external device.
