It has most features you could want and at a cheaper price than the rest <| sep |> Wait , wait , Erland ye did the vocals for Poor Leno ? I ' ve been listening to Kings Of Convenience for years , one of my favorite bands , and I never knew this . Or Whitest Boy Alive , for that matter . Apparently I haven ' t done my research . I ' ve got so much to listen to now ! <| sep |> Maybe your mouth is dry . Try swishing water around in your mouth for 30 seconds or so .
