Just wantin some good music for some videos I am thinkin of makin and some good music to practice to
That narrows things down a bit, but still needs more context.
For practice, Nox Arcana would be better as it's less distracting and more ambient. There are times when brainstorming that I prefer to put that sort of thing on my iTunes and let the free association of ideas go.
For videos, it's heavily dependent on the performance. If you intend to speak (which would be a welcome switch from all the mute wannabes I see floating around cyberspace), no lyrics. Instrumentals. If you aren't going to talk, don't just stick a random song in there. I once saw a knife manipulation video with Iron Maiden as the soundtrack. Not the best choice, but still a decent one.
Examples... Off the top of my head, a routine that somehow involves bleeding would be good to set to Wolf Moon by Type O Negative, which talks about blood a lot, but for reasons that I cannot disclose in public because it's incredibly taboo.
