A lot of classic video games music. Really worth to have a look. Check \Productions\Discography\ menu

From their about box:
The 8bitpeoples first came together in 1999 as a collective of artists sharing a common love for classic videogames and an approach to music which reflected this obsession. Our primary interests were to provide quality music for free and most importantly to have fun. In the years since, we have grown in rank and expanded our goals.

We continue to provide the vast majority of all our releases for free, including printable covers and inserts so that anyone with the desire to can "manufacture" physical copies of our albums. Furthermore, limited runs of most of our releases are available, offering superior sound quality to the mp3 releases and occasionally bonus tunes.

In addition to our continuing devotion to music, we now have a research & development division dedicated to the creation of software, construction of hardware, and dissemination of documentation related to our cause. Our love for the audio/visual aesthetics of early videogame consoles and homecomputers continues to provide us with the drive to push the medium to its very limits, and then see just how much further we can go after that ... you know, just for fun.
