and video game-inspired music, here's a pretty cheap one-way ticket right into the scene. Nubuwo is a site that's been created to cover exactly this kind of music, and over on Kickstarter they've compiled the talent of 12 different musicians across quite a few games into one big bundle for sale.
For $6, you can pick up either a 92-track "Vocal Pack" featuring the likes of Laura Shigihara, Floex, and the great Mega Ran, or a 150-track "Instrumental Pack" with the soundtracks to The Binding of Isaac, Bit Pilot, and ilomilo.
For $9, you get both of those, and for $15 you'll get 25 more tracks from excellent indie games like Spelunky and Antichamber, a couple interview segments with Final Fantasy composers Nobuo Uematsu and Kumi Tanioka, and a few other goodies. Higher donations can get you the tunes on actual CDs, and signed by the composers.
