Hey, same here. I’ve used this app for a long time (and will continue to do so, since it definitely does still get results), but starting about a month ago, every single song I download (regardless of the source, it seems) will list the song with the artist’s name first. So for example, the song’s title will be “Arctic Monkeys – R U Mine” and will be filed under Unknown artists. It only used to do this occasionally, but after several downloads with other songs and artists as well I’ve concluded that the app does this fixedly now.
Idk what happened really. It used to download songs perfectly normal – I’d download a song and it’d list the name as just “99 Luftballons” and the artist as ‘Nena’. Doesn’t do that anymore. Not the biggest deal ever really, just glad to know it’s not just me.
Galaxy S7 by the way.

Find the songs from File manager app and move all songs to the “Music” folder (or any other folder in the root directory). Some audio players don’t detect the songs from sub-folders.
