Free Offline Music Importer from Google Play Store: Was $4.02
I use the Google Play Music app and I wanted to import my downloaded music from there to my phone so I didn't have to always be online to listen to it. I've been looking for a working app for that but most of what I found weren't doing what they were supposed to do - either there were a lot of bugs or it's just not working seamlessly with the Google Play Music App. Lucky, I found this one called Sapien but I had to pay for it for like $4.02. I checked today and it said that it's not free for a limited time. This is a great app and will surpass your expectations.
