I have again the same issue as a week ago.

The problem concerns only some titles, not all.

Two examples for today : 

• ​​​​​​​​​​​​​​ Charm of Orion by Marie Bruce (and other artists).

I get this message :

 But if I search for the artist (Marie Bruce), and then the right album (Moon Chants), the song is well available :

• Castle in the clouds (Beverley Craven) 

Although in this last case, the search is successful when I add “by” between the title and the artist !

Do you have any explanation for this for this strange and annoying behavior ?

Thanks in advance
