Bit of a specific question this...

So, I listen to a fair few podcast, mostly using the standard iPhone podcast app. It does the trick nicely, I subscribe, they download, all is well with the world.

I also on occasion get a movie review podcast from another source, and they come as .mp3 files, split into chapters. When I copy the files over to my phone, they play with the Music App. Thing is, if I force close the app (double tap the home button and swipe away all background open apps), it never remembers where I was in the particular "track"/chapter. So, I either have to make a mental note of the running time when I stop listening, or try to guess where I was when I next start listening.

Any ideas how to combat this? Or should I try another way of listening to them, other than the Music app?

Any advice would be appreciated. :)
