Hey CYY fans!

We're going to be spinning back the best of the best the week of October 14 by bringing the top 500 songs ever played on the station. It's going to be an epic time and celebration of all that is CYY.

But to make this event even sweeter is the amazing prize we want to give away to a lucky person: a pair of tickets to see Tool November 14, 2019, at TD Garden and a pair of tickets to see Green Day, Fall Out Boy and Weezer August 27, 2020, at Fenway.

Oh, and that person will also win 10 of the greatest alternative rock albums of all time, courtesy of Bull Moose.

Pretty sweet deal, right?

Here's what you have to do:

Download our app. This is where our exclusive contest entry form will be - on the app.

Download The 94.3 WCYY Mobile App

On Saturday, October 5, a button titled "CYY 500" will appear on the main page of the app. Click on that button to be taken to an exclusive page where you'll fill out a form with your info, and, most importantly, you'll make your guess as to what the No. 1 song will be for the CYY 500.

All of the people who guessed the No. 1 song correctly will go into the drawing for the grand prize of the pair of tickets to both Tool's show and the Green Day, FOB and Weezer show and the 10 alternative rock albums, courtesy of Bull Moose. One winner will be randomly selected from that pool of correct guesses.

So make sure you download the app to enter the contest and make your guess!

One entry per person. Contest ends October 16.

The CYY 500 countdown kicks off Monday, Oct 14 at 10 a.m., so make sure you get your guesses in and be sure to tune in!
