Since I've seen many people complaining about having to go through each album to add it for offline listening, I figured I'd share a simple tip:
When browsing "My Music," switch over to viewing by genre. At this point you can make each genre available offline in the same way as a single album, which should save a lot of time for those trying to make their entire library offline-accessible.
