Getting clever with Blogger? An appeal for help!

Guys, and Gals, in the wider blogging community, I am looking for a little help in ways to jazz up my blog posts a little...

One thing I would like to do is to be able to use more interesting Fonts on my blog posts.

For example, how would I add more options to the Font drop down menu in New Post, see pic below:

More Fonts wanted!

I am aware of Google Fonts but can't figure out how to add them to this...

Another thing I would like perhaps, is to create a little 'mood' with certain blog posts, via musical accompaniment. I don't just mean a Youtube video clip in the post you have to click on, but something a little more automatic, such that once a blog post is clicked on to view, its accompanying music will start to play automatically...

I've got a bunch of movie soundtrack stuff on my Ipod, and for example having an excerpt from say Sherlock Holmes playing alongside a Empire of the Dead post could be quite cool I thought...

Any clever people out there who can help please, comment below, or email me ( Email link in sidebar below Pirate picture).

Cheers and happy blogging!
