Hey everyone

I just installed Foobar on my phone with a 200GB micro sd card (legit Sandisk) with over 16 000 AAC M4A files.
In settings, then Media Library I've choose the external storage.

But, it's been indexing since at least 4 hours. How long is it usually? There's no progress bar anywhere, I'm not sure if I should click rescan or still wait.
