[SOLVED] moOde 9.0.5 and 9.0.7: Adding radio station to playlist does not work

[Tim Curtis]

So what is missing from our attempts to reproduce this bug?  I mean how come kurt1970 could get it almost at will but the rest of us couldn't?

It was not obvious at all but whenever the Queue rendered, for example a new track started playing or station metadata updated it would overwrite a variable that was also reused by the add_to_playlist routine to store the path of the item to be added. 

@kurt1970's issue would occur if the Queue updated after clicking "Add to playlist" and selecting the playlist but before  clicking Add.
