When I search certain songs from artist Djavan (Flor de Lis and Oceano are examples) it is like Spotify has hidden them. There's an album of him called Djavan, for example, that has 9 tracks and it only shows two of them. I noticed this today (January/ 28) and as far as I looked for solutions, it's a problem with the tracks of this artist only. The artist haven't removed any song of his discografy, neither have I hidden any song of his. I tried searching by different devices and accounts and it's a common issue. That is not a problem with my internet connection.
