Crash on current and tracks|list when playing internet radio

[addisonamiri]

I'm listening to lainchan radio and musicbot crashes when I try to get the current track. Both the current command and the tracks/list commands crash the program. This is the only song in the playlist if it makes a difference. Here is the output of musicbot. I'd give it a whack myself but I've never touched go before. Thanks for the project though. Even if I can only play from spotify it's pretty cool.

[sosedoff]

Thanks for the bug report, i will look into it.
