Songs are correctly tagged with album, artist, track, etc. and in the same folder with the rest of the album tracks but three or four of the album's songs are not listed with artist/album in library, but rather under Unknown Artist/Unknown Album. Checking tags from there in poweramp shows all information accurately. Checking album folder in Folders says folder contains too few songs, reflecting incorrectly listed songs. Songs play fine, but tags seem to be being ignored for some reason. If it helps, song filetypes are flacs, are stored on a new 32g sdcard. Tried deselect autoscan in settings and rescanning manually, no avail.
