Playing 2 Songs on Mobile and mix them?

Heyo everyone,

I’m currently trying to have 2 songs play at the same time in a small mobile game, one muted, one playing. Let’s call them song1 and song2.

Why? What I am trying to achieve is:

If a certain amount of points is reached, then the game mutes song1 and unmutes song2 (via volume multiplier). The thing is, both songs are basically the same, one a radio-ified version (song1), the other one the normal version. (song2)

So far, the brutish and plain attempt I tried only works flawlessly on PC. On Android (using a HTC One M8), song1 mutes when the condition is reached, but song2 starts from the beginning instead of playing from the same spot where song1 in terms of minutes or seconds stopped.

Is this a hardware limitation from mobile devices and/or a limitation from UE4 (so far?)? Or am I just doing something horribly wrong?

Cheers,
