small "defects" as almost every player - but recommended

Works 1A. The only thing I also notice that the battery will be drained quickly. (I'm going to see if it is with other players as well. Use otherwise mostly Spotify.) How do I see the wave / colorful artwork, unfortunately I have not gotten out. The audiobooks can be seen in the list, I do not find that great. But is also a problem in other players. Something I'd rather be able to decide for themselves whether it is to be displayed with or not. Only in English - might also be in the store. Would still beautiful with language.
