I'm going to be making some lyrical icons soon and for that, I have a community I made a while back called lyricsforicons. It's been inactive, yes, but I'm hoping to start it up again. I know people have certain lyrics they would love to see... well, instead of posting them in comments here, which the entries can eventually get lost... journal that community and post them there! :)
It's not only for suggesters but also for also for any other icon-makers that are looking for inspiration.
Right now, I would definitely love more ideas posted there since I'll be making more icons soon.
