actually on my case, it is sending a sample from song (wave sound) and service recognizing song, and then it is updating all tag info (album, year etc) so basically it should work even without year info (i tried it with few tracks and it works without gender and year) it gets two new info fields like gender, these are artistlink, which is for example "progressive rock" and artistlinkwide "rock" so when you do search for link, first it lists all "progressive rocks" and if you widen your search you will see all "rock" thats why I see placebo and britney linked when I widen lol PS: I started to work on a Windows Media Player plugin for A1000, will try to finish on weekend (to synch my device) I don't know much experience about digital music, so you can always PM me your ideas
