Is My Blog Screwed Up?!?!

okay, so Gina kept telling me that my blog settings were messed up and i didn't believe her until i went over to her house and saw it for myself. when i look at my blog on my computer everything seems normal, but when i saw it on hers it seems that i have 2 playlists that play and a huge long html code at the top of the screen!!!! she told me that she figured that i have 2 playlists running because i have like more than 200 songs on them so it had to use another playlist. If anyone else has these same problems, please let me know so that i can fix them!!!!
