Usually I have to remember and type out the full genre name, the current auto-completion is usually not what I want. I use non-standard Genre Names like 'Soul/R&B' and 'Disco/Dance'. Currently, for 'el' it suggests 'Electro' instead of 'Electronic', which is a more common genre.
A solution for this issue could be inserting an MRU list with maximum 10 items in the beginning of the standard genre list dropdown and include that in the completion.
