Thank you for your suggestion, but I thought there was a simple option to simply sort by artist names automatically, but if we just can't I can live with this!
Setting a number for each song would mean adding a new number every time I download a song (which I don't really mind). But if the song I add is number 45 on 90 songs, I will have to change the number for each songs after the number 45 so there are no duplicates. If i don't there will be two songs with number 45.
And I often download many songs at the same time.
I don't know if what I say is clear enough, but it will be a pain in the ass to change the numbers every time I download a song.
Thanks again sir for your time and help! Also the quickness of your answers. I appreciate that.
