Deletion of List of UK top 10 albums in 2018

Comment: I find it puzzling, what exactly is the rationale for a list of top 5 (rather than top 3, 12, 20, or whatever number)? If it is something randomly chosen by the editor rather than something that has any significance, then I would vote for delete, but I would like to hear an explanation first.  Note that per  {{tquote|One accepted reason why a list topic is considered notable is if it has been discussed as a group or set by independent reliable sources}}, are there sources for a top 5 UK list
