I have both, the album art embedded into the Mp3 files and the JPEG file (it's not hidden though) due to the fact that not all mp3 players (on PC or portable) accurately read embedded tags in particular those with Unicode characters such as Japanese, Hindi and Aramaic. I've likewise found that both a clean folder structure (i.e. D:\Music\Artist\Album\Track Number - Track Name) including the .jpg increases the compatibility, readability and it looks nice. That way, until the feature appears, I'm not stuck with missing tags or album art. Also, if you use Tag and Rename, the resulting JPEG file isn't hidden. It isn't recommend that you keep ALL your mp3s in a single folder, even if its just singles, since it does prevents things like Game Ex downloading appropriate album art. Your Operating System takes less time to read a directory containing ten folders then does for it to read a single folder containing 1,000 mp3s (people with lots of ROMs in their setups probably know what I'm talking about). Many of the programs (if they don't check for embedded album art) will want to look for the album art in a singular folder that contains only the music files associated with the album/single. Oh, also making sure you ONLY have the Mp3 tag version ID3V2(2.3 or 2.4) and NOT ID3V1 tags makes life a lot easier to.. because I've notice iTunes, Windows Media Player, Winamp and GameEx might read half of the tag in ID3V2 and half of the tag in ID3V1, even with the option to skip the ID3V1 tags enabled. GameEx may only read the text from the ID3V2 tags, but it will read the CORRECT ones and not the truncated ones from IDV1 tags. This is not a flaw in the program but to the way tags are sometimes embedded into the files themselves. One last thing, having the JPEG in the folder, means that you aren't stuck to ONE type of music file. You'll get album art for OGG, FLAC, and WAV files even if you can't embed them into the files themselves. Classical music is a great example of a type of music that degrades greatly when compressed to Mp3. The last benefit of doing so, is that when you become a registered user of GameEx, you get to browse by FOLDER which is AWESOME, and having the JPEG in the folder, it speeds the loading of the album art since it doesn't have to get it from inside the file. True its only milliseconds, but that adds up =b
