You can do it by navigating to the favorites section and entering the downloaded music section . You will have to turn the “Downloaded” toggle off for each of the albums/playlists you wanna delete

No. I think you just go under settings and click Data And Storage and click Clear All. Or if not, I’ll try rechoosing the storage location and that should erase them all. I found this out after asking the question.

Follow the these points hopefully your matter will be resolved:

1. Insert your SD card into your computer or phone.

2. Locate the music files you want to delete. Depending on the device, they may be stored in a specific folder, such as "Music" or "Media."

3. Select all the music files you want to delete. You can do this by clicking and dragging your mouse over all the files or by pressing "Ctrl + A" (or "Command + A" on a Mac) to select all files.

4. Once all the files are selected, right-click on any of the selected files and choose "Delete" or "Move to Trash."

5. Confirm that you want to delete the files.

6. Wait for the deletion process
