I listened to all three songs that you posted. The fan-made video for "Never Neverland" is very beautiful.
As far as their music is concerned, I agree with your statement that they're a bit different from the typical German electro bands. They're a bit too trancey or, as you said, house/dancey, for my taste. Also, I'm not a big fan of Andre Hartung. As you know, he sings on "Never Neverland" and "Das Kraftfeld." I remember reading some great things about Sero.Overdose, and without even listening to samples, I bought their "No Time For Silence" CD. I couldn't get in to it, because I really didn't care for Andre Hartung's vocals. However, I did enjoy Stefan Leukert's vocals for "Fehler 404." I've never heard of him before.
Also, I guess that neither guy in the band sings. It looks like that they use quite a few different guest vocalists for their albums.
