PwrBk to PS3 - Music

Hi all,
I'm new here, so go easy if you will...

I turn to you masters out here for advice.

I have all my music iTunes on externals drives that I run on my Mac Book Pro.

Is there a easy way to get my music to play through my PS3 via my MBP?

I have tried PS3 Media Server and really had no luck, not sure why?

Never seems to connect...

Any other EASY option?
Thanks,
AZAVJ

Thanks Chef - I am kicking "Playback" around and it seems to freeze up once your music starts playing. Music plays but you can't exit it...
Not sure what the deal is.

It's a demo...

I will check out "PLEX."
