first, the lyrics...you have to do this in iTunes similar to the way you would add album artwork. highlight the song you wish to add lyrics to and go to Get Info (right click on a pc or ctrl click on a mac). you should now see a tab for lyrics...select this tab and past the lyrics in the open space. click OK and thats it.
now, about the web links...this is much easier although can take a few tries to get it right. open a webpage, tap the + on the bottom of the page and you'll be prompted as to what to do next. i suggest focusing in on a specific section of the page as this is what will become the icon.
hey brocly, gotta thank you man. i didn't think i'd ever take advantage of this feature but i tested it out after replying to your post and it's pretty cool. leave it to Apple to make even the simplest function look dope.
about the icon. I was making one and said "whats he talking about ? Its hella easy and i got it right the ...well hum I didn't like that pic. try again. well that one not good eather. the 5th try, bingo. I see what he's talk about. hehehehe"
