Music format support on Nintendo DSi

Today I bought a new microSD card for my phone.  My son also wanted a SD card for his Nintendo DSi.  He wanted to use it to put music on for playback.  So I figured that I would give him the 2GB card that was I was using in my phone.

When I copied some mp3 files to an SD card, and they were not playable.  It looks like the Nintendo DSi only plays AAC files.  On their web page they link to the Nero software where they sell it for $6.  You can do the same thing for free with iTunes.

Parental Controls and SqueezeCenter

We have installed Squeezebox Booms in each of the kids' rooms.  This works great to be able to access all of our music in their rooms.  The kids like it as the presets are set to various childrens music, so they can easily listen to any of their music.

The problem is that our son is starting to explore our music. Some of the content is rated as "explicit", and we really would not want him coming across the music.  Now I am going to try and find a solution that would let me specify a list of artists that shouldn't appear on a given Squeezebox.  If this doesn't exist, I will look at writing a plugin to create this.
