An enhanced compact disc (ECD) is an audio CD with multimedia content that can be played on both audio CD and computer-based CD-ROM players.

Extended Play goes back to the days of Vinyls, when there were different sizes and different turntable speeds, for example there were two common speeds, 45 and 33 (meaning RPMs) and, generall, two sizes of records, 8s and 12s (meaning inches).

EPs were like a single, but with more songs. LPs were full-on albums.

Many artist, to this day, still make vinyl masters, because nothing sounds like a well-mastered vinyl played by for the first time. They have unparalleled frequency response (unless we're talking 4-track reel-to-reel, here).

LP means 'Long Player' and usually implies that it's vinyl (a 12" record.)
