No no no, fucking no. I didn't want a cell phone and then I had to have one for work and now they want my biometrics? Every bit of identity and every ha'penny you have must be accessible and on display at all times with this fucked up society. They won't be happy until we're all just walking around naked carrying every dollar we have fanned out in our hands so it can be counted faster.
Music is a good one. Especially electronic instruments, mostly because you can play and record with headphones and it's easy to get a lot of different sounds to play with.
