[iOS][Radio] Song radio playlist refreshes before I've finished listening

[user-removed]

So lately I've liked to use the radio feature to choose a song and let it create a playlist around it.

BUT, I can't even get through the playlist before it refreshes itself, which leads to things like songs repeating almost immediately or other songs I wanted to hear dropping off before I've heard them. Sometimes it actually refreshes itself while listening, which has also caused the playlist to stop dead.

Is this normal for these to refresh THAT frequently. I mean, this is within an hour or two of starting it.
