A blog with MP3 hosting. How do?

I have an idea for a blog/website where I post my own music and write about the music theory/arrangement and mixing/mastering techniques behind each MP3 snippet. What's the most idiot proof way I should go about this? My ultimate dream is "mydomainname.com" (which I am comfortable paying for, plus MP3 hosting up to $100 a year or so) where I log in, write that day's post, upload an MP3 (never more than 5mbs) and click "enter".

While not a complete web novice, I've only used dreamhost in the past for personal projects with very (very!) light css and html but I would prefer more of a "template" type site that doesn't involve uploading things through ftp servers. I'd also prefer the MP3 to be hosted locally rather than soundcloud, Dropbox or some other 3rd party.

Does such a thing exist where I can:

- hit a bookmark in my browser
- write some text
- upload an MP3
- click "enter"
- my post appears
- light moderation to delete the spam comments, revise posts

Would prefer to avoid tmblr, blogger et al, a stand alone website. I truly don't care about eyeballs or readers, I just want to move away from my soundcloud account and talk about my music motifs on a standalone site.

Walk me through this like I'm your grandpa, any ideas?

Thanks in advance!
