Destiny Covenant Ministries - Anyone else having issues streaming music (stops playing)

Hi,
Pandora, Slacker and Spotify all stop streaming, or start to have breaks in the music until they eventually do stop streaming, a short time after the screen turns off (maybe one or two songs). It's incredibly annoying, and a massive oversight on the part of Google/Samsung that this phone can't seem to handle this most basic of functionality.
Is anyone else having this issue?
Please help.
I didn't find the right solution from the Internet.
