something strange happens when playing media content on iOS

Hey guys,
So I usually go on a site that plays MP3 audio uploaded by users, including me. It's basically an open source mp3 uploading platform by Sam Tupy.
Anyway, that's not what I came to write about. I wanted to see if anyone else was experiencing this, not just Safari in general, but other web browsing apps as well.
So, here's the bug/issue I'm having. I can select the play button and play the audio for as long as 2 or so minutes, before it goes quiet. Not only that, but the website has a download audio option, so I try that. But safari skips around in the audio, sometimes going forward a few minutes, or jumping about two minutes backward, repeating the same audio played.
So, is anyone in this community experiencing this?


Some questions

I’ve had something similar happened to me quite regularly, and I have some questions for you, if you don’t mind answering.
Firstly, what happens when you lock the screen while playing an audio file, does the file stop playing or does it continue?
Secondly, what happens when you double tap the screen with two fingers the magic tap gesture to restart playback after it has paused?
