To answer your question I need to know the context of where you are
trying to grab this value. Is it within an anonymous function?
Within the infamous $().ready() method?
Moreover, this:
var song_val = jQuery("#playlist_songs_"+editRowID+"_song").val();
is perfectly valid syntax in jQuery. So your problem is not there.
However, your problem sounds closure related so show so more code or
post a link and I'll help you out.
Cheers.
