Deeceekayzed,
Thank you for returning to the Apple Support Communities with this information. We appreciate these extra details. First, your iPhone does look like it's eligible for an update. Here are some guides with information on how to create a backup of your iPhone, then update the software:
Once the iPhone software has been updated, check the App Store for any available app updates. If you see updates, complete them, as this can help correct the issue. If the problem persists and is only with one or two apps, you may want to reach out to the app(s) developer. Here's how: How to contact an app developer.
You mentioned that the problem seems to happen only with music that is streaming. Does this vary by location? If so, this may be an indication of problems with the cellular/data service in your area. You would need to reach out to your wireless provider for more support with their service.
Cheers!
