My recommendation for everyone is to use Fastmail and a custom domain.
Fastmail is extremely reliable, and since they charge money they also offer customer support. A few years ago I lost a lot of emails due to a client bug, and Fastmail support was very helpful recovering them from backup.
Use a custom domain so you can change providers in the future so you're not locked into your provider and can change if you aren't happy with them anymore.
I'm not sure if it technically counts as electronic music, but I really liked Aphex Twin's Computer Controlled Analogue Instruments.
The effort that went into recording it must have been enormous, and I wish I could have been in the room when the tracks were recorded.
Courts aren't limited to prosecuting crimes that happen in their jurisdiction. For example, German courts are prosecuting sex crimes committed by tourists in Thailand. So just because there is no court nearby doesn't mean you can do whatever you want.
I think Signal is trying too hard to be secure, and they are missing a lot of convenience features.
For example, you can't migrate from Android to iOS or vice versa. You'll lose all your messages and groups.
Or it's really hard to export all the photos someone sent you. I get that my iCloud library isn't as secure, but I really want to make sure I don't lose those photos if I lose my device. The photos aren't that sensitive.
The security notifications are also well-meaning, but hard to make sense of. You sometimes get notifications for changed security numbers, when people change their phone, sometimes folks show up twice in groups, etc. It's all a bit hard to understand and difficult to use.
And finally, it seems that messages are sometimes delivered a bit unreliably or with a long delay.
