they said it as if they were goign to do the same thing, a free basic player and a better feature pack, who knows tho maybe only the feature pack ppl will get the WMA and OGG fiel support, if thats the case then teh 20 will be worth it, as far as the ID question goes, im not sure, but pocket player has this feature:
"Possibility to change ID3 tags of MP3 files (set track title, artist, album, etc.)"
good luck
