ID3 tag database vs. Odyssey
Tinroad has it backwards. >>>
"The Gateway spec sheet for the DMP-X20 clearly states that it supports ID3 tags. I see no mention of database support, but such databases are really needed only for less sophisticated players that lack a multi-level directory structure."
Less sohpisticated players use a database? No. Tinroad doesn't understand this issue, but it is simple :
MP3 Players with an ID3 tag database allow the user to search/browse for music by looking through a list of arists, albums, songs, genres, composers, years, etc. When you add music to the player, the database is automatically updated.
A directory tree structure is primitive in comparison. You can look through whatever directories you have on the drive, and that's it. You can't browse or query any dynamic lists as you can with an ID3 tag database. Its like looking through an external hard drive instead of a pocket jukebox. A file/tree structure is much easier to implement for the developer, but most consumers prefer a library database.
The only players still using a file structure-only approach are the e.Digital 0dyssey and Archos-brand players. The Archos players are better than the Odyssey, however, since you can store music in ANY directory. Odyssey requires users store music in 2nd-tier directories ONLY. This is an overly-constrictive scheme, but it may be a limitation of e.Digital's "MicroOS" platform. It's just outdated and simplistic next to the competition.
ALL the other brands - Apple iPod, Creative Nomads, Rio Karma, Phillips, iRiver, RCA, Samsung, Dell, Toshiba, etc etc use an ID3 tag database.
Apple iPod, the best selling and easiest-to-use player, has always structured its music library as a database. Apple did its homework, gave people what they want, and in return then have had great success with it.
