Playlists can only show songs that I like.

So when I play Global Top 50 or Hip-Hop Central it only shows the song that I like.

Hey @YSQ

I'd suggest taking a look at your hosts file to ensure there are no Spotify-related entires in there. 🙂
The file reroutes network traffic, so when there is a Spotify entry in the file, the traffic is rerouted, not reaching your client and thus creating issues.

Try this:

1. open Notepad as an administrator (right-click - Open as Administrator)
2. go to File - Open and navigate to

C:\Windows\System32\drivers\etc

3. Choose "All Files" instead of "Text Documents" next to the File Name box. You'll see a handful of files. Pick hosts and click on Open.
4. The file is opened. You will see a block of text with # in front of each line and might see entries like

0.0.0.0 website.com
127.0.0.1 website2.com

Check for any entries with spotify or fastly in the address. Examples may look like:

0.0.0.0 weblb-wg.gslb.spotify.com
0.0.0.0 prod.b.ssl.us-eu.fastlylb.net 

(and any variations inbetween)
5. If you do find any, you can delete the line. You can also add a # in front of the line, that's 'commenting out'.
6. Save your changes. Restart Spotify.

Let me know how it goes 🙂
