I recently set up a new phone and I was shocked that I got a notification from SoundHound. That's one app that has no business trying to "engage" me - it's there for one purpose, identify songs when I want it to. If it's once every two months, that's all the engagement they are getting. There is no retention to be had, and I will not give them any.

If Android didn't allow blocking notifications, then any app that does this would get the boot. Youtube, HN and eBay is stressful enough to follow, I don't need more of this in my life.
