Chrome, but I think it has something to do with the content of the search.
Maybe it's just slashes that create a problem.
That could well be the case.
If this is really important to the OP he could try some regex stuff to try and
accommodate for that, and perhaps other exceptions.
Or, just create a google search including 'deezer' and <artist> etc.
The result will probably only take one click extra to reach the correct page on deezer.
