I have a feeling that this song is only performing ho-hum at the moment due to the video being a little, non-existent in terms of impact and that other songs such as, Get Lucky, Blurred Lines, Radioactive, and Come and Get It are improving on radio. Possibly just hanging on before surging within the next two weeks. Bruno is the king of longevity (almost all the time).
UK iTunes
10 & 82. Treasure - Bruno Mars
Almost #9 combined.
It's 10 & 85 in Canada, #9 in France, #14 in Germany, #12 in Netherlands, #13 in New Zealand and #20 in Italy & Australia.
He's doing great, even with that video.
