The Unofficial Alt18 features the Top 18 songs from the weekly Alt-18 Countdown as requested and/or voted by listeners of Alt Nation on SiriusXM (channel 36).

The Unofficial Alt18 (briefly The Unofficial Alt8 in 2018) derives from the Alt-18 Countdown results being posted in a discussion board on the Alt Nation Facebook page. Soon after Spotify came to the USA, I began putting those weekly results into a playlist and it started to catch on (over 5,000 followers to date). Facebook subsequently removed discussion boards in favor for their new timeline layout and the weekly results went away. I took it upon myself to create a Facebook page to replace the discussion board posts, and now this site, the Unofficial Alt18.

Results and Playlists are updated and posted on Saturdays, usually immediately after the first airing of the countdown show (1:00 PM ET / 10:00 AM PT). New Music is posted on Tuesdays, Most Airplay is posted on Thursdays and Songs to Know is posted on Fridays.

All posted content and times are dependent on availability of data.

The Unofficial Alt18 only exists with the help of it’s members. It costs around $500 a year for web hosting, subscriptions to maintain playlists on Spotify and Apple Music and a subscription to SiriusXM. This does not include the cost of my time to maintain it all.
