My family is noisy as well, I have to wait till late at night, I use headphones. You can also use a phone that can go on to YouTube and get music from there. I do that at midnight when I have powered down my computer. Invest in some really comfortable headphones, the kind that can help block out sound.
I use Dub-Step or something chaotic sounding for Loki. Other than that, I just use the meditation music on YouTube.
