i need a tiny bit of artwork (tiny both figuratively and literally)

first, i want to be clear about my intentions. i am working on an addon for the open-source media player called Songbird (based on the mozilla/firefox framework). i have almost all of the programming done for the addon, but i need two tiny bits of artwork to give it the final touch.

i cannot offer money. what i can offer is a contributor mention for the addon, which should achieve some degree of notoriety. there are no other contributors, so your name would stand alone with mine on the about page and the page on http://addons.songbirdnest.com/

second, the addon is called Virtuoso, which both imitates and improves upon the functionality of iTunes' genius function (generating a playlist based on a single song of tracks that are both highly correlated to the original song and likely enjoyed together). it works great, and will likely be mass-downloaded

1) i need a 32px by 32px icon (to be discussed for a design) to represent the playlist.

2) a set of toolbar icons (18x72, or, more accurately, four 18px by 18px icons stacked vertically) to represent the various states of the action button. the design of this should logically flow from the design of the above.

these examples are from other addons, so i cannot blatantly rip them off. if you can help, ill be available in about an hour on AIM (authorblues), gTalk (authorblues@gmail.com), MSN (authorblues@gmail.com), email (authorblues@gmail.com), or IRC (#ngprogramming on irc.freenode.net)

thank you in advance for any offers to help me contribute to the open source world!
