Fix please

Most of my songs say null playing next song and also there are way too many ads so I would like if you could fix the null and reduce the amount of ads -- But the songs can still play while your phone is on the lock screen which is good so you dont have to waste your battery sometimes the app glitches out but for the most part it would be a great app if they fixed their songs so that they werent null.
