MP3 Music Collection is a pirate label. Produces 1xCD or 2xCD MP3 CD-ROM compilations, which contain several releases of a given artist(s): all albums (released to date) + selected singles + live recordings and bootlegs.
Releases come packaged in Jewel case, and recently also as Digipaks.
Some releases have several Jewel case versions (with different artwork and sometimes different tracklist).
Releases come with colourful artwork and picture-surfaced, almost always factory pressed CD-ROM disks. Disks usually have "PD xxxxx" in the matrix number, where "xxxxx" is a 4 or 5 digits number.
Releases can be recognised by a specially designed "MP3" logo on spine - the word "MP3" printed in bold white above 4 red horizontal lines.
Label's main logo is missing on spine (appears on front\back cover and disk).
CD-ROMs contain shell, WinAmp player, m3u playlists.
Some releases also contain music videos (in AVI or MPEG formats) as a 'bonus'.
