I did some programming a long while ago (for a personal mp3 player much like the one Hugo first made in his car) on a screen smiliar to the empegs only it was a character based vfd. The first version of the software I put out scrolled the mp3 info just like you mentioned, the problem is that without making it pause at certian parts it can get kind of obnoxious to read.

One thing i noticed though is the text on the "text visuals". If i shutdown my player when its using one of these visuals and reboot it, the text comes up with the developers not the song information. While this is kind of cool that they did this it can be very annoying when your expecting it to be the song information bumping to the music not a bunch of peoples names. Once I switch to the next song all is well and it displays the song information.
