Though it's totally convenient to buy all your Vita games on PSN, there is sometimes an advantage to buying them retail. In the case of Lumines: Electronic Symphony, when ordered from Amazon, that advantage entails three exclusive MP3 downloads.
Purchases of the puzzler from Amazon will come with three MP3s by composer Makoto Asai, from the game's "secret unlockable stages." Amazon has the release date listed as February 14, in time for the early First Edition Bundle.
Aside from the Q? produced tracks, artists with music in Electronic Symphony include "Kaskade, LCD Soundsystem, Chemical Brothers, Bebel Gilberto, Goldfrapp, Josh Wink, Safri Duo, Amon Tobin," and more.
