If you wish to use the songs you found on the net, please download them and make sure you save them to your iTunes music library. You can browse and check if you have the songs available when you connect your iOS device to a Mac / PC. Open iTunes and you will get to see the list.
Tap "Make Available Offline" in Music App, make sure the music is completely downloaded. And you're good to go!
If you worry that the volume of the loaded songs can be too high, you can tune the volume knob in Jam Player a bit lower before loading. You can do so when you want to practice with a backing track, or avoid the sound blasting your speakers. This wouldn't affect the total output sound at all.
Make sure you are logged in with the same Apple ID. AppStore will not charge you twice for any purchase, as long as you are using the same Apple ID.

Q: What is the difference between using JamUp as IAA and using JamUp plugin in Auria?
A: If you're using Auria and hope to use JamUp with it as a plugin, then you need to purchase the JamUp pack in Auria's in-app purchase. However, if you already own JamUp / JamUp Pro app (on AppStore), they can be loaded and used on Auria as IAA files. Please notice that JamUp (in-app plugin) in Auria is only available in Auria series. If you wish to use JamUp / JamUp Pro as individuals, you will have to purchase them on AppStore.
Q: Is JamUp and your other apps available on Android?
A: No. JamUp and our apps are only available on iOS. Our desktop products are available on Windows and Mac OSX.
Q: What is included in All Access Pack?
A: If you purchase All Access Pack, you will get literally all of the amps / effects in JamUp. And you don't have to buy any other packs.
Q: Can I use my Bluetooth speakers with JamUp?
A: In order to make sure we reduce the potential interference and latency as much as possible, we have disabled this function. So that JamUp can work smoothly with MIDI controllers and work with low latency when recording through audio interfaces.
