After protracted deal-making with the country's record labels, Spotify has finally launched in Japan. To sweeten the deal to prospective listeners, it's already putting particular focus on the service's lyric display feature -- and the karaoke possibilities that (vaguely) come with that. But what's another country in Spotify's empire? Japan is the second largest music market in the world; Bloomberg pegs it at around 300 billion yen (almost $3 billion). The country continues to sell physical music media like CDs well -- it's the country where Tower Records stores still lives on. Spotify Japan has launched both a free ad-supported service as well the typical 980 yen per-month ($9.70) subscription -- it's in invite-only beta for now.
