I totally forgot about this thread. Sorry guys!
Anchor doesn’t really have any restrictions to what and when you can post (at least not that I know of). You can either record yourself on the app, post audio files from your desktop, post audio from YouTube and SoundCloud, or post songs from Apple Music and Spotify, and they stay up for 24 hours. It is kind of a pain to find time to post and record, but other than that it’s pretty easy.
Sadly the Eight Muppets Notes station and tumblr blog have both been dead for the last month or so, because I got really busy with school and work, and then I went to Germany for ten days, and now I’m back to being busy with school and work. But they’re definitely coming back soon, especially since it’s almost time for Christmas music!
