"The real 'top 66' method is using SoundCloud's RSS feeds. Every artist has an RSS feed at feeds.soundcloud.com/users/[user-id]/tracks.rss – you can play those in iTunes or any podcast app, which schools never block." – u/musicarchaeologist

Some older firewalls only block https://soundcloud.com but not the raw IP or alternative subdomains.

While the urgency to hear the latest track is high, you need to be aware of the dangers associated with free, unverified "Top 66" proxy lists.

If a specific "66 top" site is down or blocked, you can use these reliable methods: VPN (Virtual Private Network) : Tools like Windscribe
