MyNoise is probably my #1 pick for most outstanding website period. So clean. So functional. So attentive to detail. So beautiful. Such care in assembling the generators. So varied. Free of ads and tracking. Freemium with a pay-what-you-want lifetime subscription. Gentle reminders to donate if you use the site a lot.
It's just one of those sites that focuses on one thing, and does that extremely well, without trying to extract as much money from its users as possible. Rare thing nowadays.
Damn I need to drop another tenner.
