8tracks is currently only available in North America. I'm hoping in future they'll restore service to other countries, but for now if you live elsewhere, you can listen using a VPN set to a US IP. I recommend: Psiphon (free), Windscribe (free), or Tunnelbear (paid, with a small free tier). As far as I know, these are all good in terms of safety and privacy, but please research any VPN service yourself before using.
You can also try any alternative playlist links, like Spotify, where I've provided them.
The Listening Booth is a section of Spiked Candy where I simply share a track I'm currently enjoying, without any writing or context. The latest Listening Booth pick appears in the sidebar of any blog post, where you can directly play the song.
You can view and play all recent picks on the main Listening Booth page, and flick back through for earlier picks.
The posts don't show up in the main blog, so subscribe to The Listening Booth RSS feed or bookmark the page to keep up with new posts.
