i just wanted to say fantastic idea!
i think i have a few suggestions for improvement. mainly, just more customization.
is there any way to make this gadget larger? i would really like to see the Song Title, Artist, Album Title, Year, Genre, maybe some other stuff without having the flyout. Can the number of vertical pixels that the gadget take up not be edited?
also, any way to change the countdown till the next song to some other field? it would be nice if we would see a countup if we wanted. or even a [time elapsed/[total time] format.
what about the cover art? any way to make it fill the whole gadget? what about get rid of that part altogether?
could even have 2 instances running to where the top instance was cover art, and the second instance was able to contain many more lines of text. although i think this would be a bandaid and the better solution would be to change the size of the gadget and just give full costomization as to how many lines of text you want, the size of the cover art, etc.
very nice though!!
