Well, I guess through trial and error, I figured it out.
Just incase anyone else was wondering:
Music 4.2.5 ( used display the widget, continues to work just says "can't display widget" on the quickwindow)
Music 4.1.11 (won't play music unless installed)
Clock Widget (digital/analog clocks)
Weather 22.214.171.124 and Weather Theme 126.96.36.199
My assumption, but not through testing is that you could remove any of these if desired, it would just say tat it can't display the widget for that page.
Sure would be nice to replace these, I personally use Google play music so don't really have a desire for another music app on the phone, but at least I can hide the icons.
