If you prefer to keep your music off Google Play Music for some reason, like being able to use some other music player, any music program for PC not named iTunes can sync music back and forth between your phone and computer. No experience on Macs but if the PC version has a feature then it probably has that too.
I've tried Windows Media Player, Winamp and Musicbee, among others, and they all can rip CDs, manage playlists, and sync to any Android phone.
There's really no official platform like iTunes for Android because all other existing programs work with it. It's kind of no point for Samsung to spend money to make a competing program that a lot probably won't use because there are already far more mature and stable alternatives.
You can also look to Samsung's Sidesync and SmartSwitch programs for PC and companion apps to manage your phone.
