Deleting 1000+ favourite songs at once (not possible!)

Limit for your favourite songs seems to be 10.000, which is fine.

Untill you want to delete them all from the favourites list. In the web interface, you have to manually delete songs untill you hit 1000, only then you can use select-all, and delete the last 1000 songs at once.

Simple fix would be limiting page size to 1000 songs or just let deezer delete the first 1000 every time you select. Now, it just does nothing.
