Long songs not if the same spot left off when you go back switching to other apps

I download radio shows like Howard Stern and listen to them on my iPhone. If I stop a song and switch to use another app like the camera, when I go back its lost its place and starts at the beginning. This did not happen with previous iOS versions.

Its annoying because I have try to scroll back to how far in on a 4 hour mp3 I think Im in. Is there any way to prevent this or is there an app to help bookmark long mp3's when switching to different apps? Sort of how a podcast will pause and remember where you left off when switching to apps like video or the camera,

Thanks in advance...
