Windowsのとき使ってたmp3ファイルをRhythmboxで再生させると曲名やらが文字化けするので直した.
まずはhttp://d.hatena.ne.jp/over80/20100224/1267021620 を参考に端末で
$export GST_TAG_ENCODING=CP932
とし,環境変数を設定.
これで直るかと思って端末でRhythmboxを起動すると

ってなったから,今度はhttp://ubuntuforums.org/showthread.php?t=1592270 を参考に
$sudo apt-get remove rhythmbox-ubuntuone-music-store
ってやったら,めでたく曲名がちゃんと表示された.
