ITEM 1.     Security and Issuer.

This statement on Schedule 13D (the "Statement") relates to the Class A common
stock, par value $0.01 per share (the "Common Stock") of Cumulus Media, Inc., a
Delaware corporation (the "Issuer" or the "Company"). The principal executive
offices of the Issuer are located at 3535 Piedmont Road, Building 14, 14th
Floor, Atlanta, GA 30305. This Statement supersedes the statement on Schedule
13G filed by the Reporting Person on February 14, 2006 (the "Schedule 13G").

ITEM 2.     Identity and Background.

This Statement is being filed by Chilton Investment Company, LLC, a limited
liability company organized in the state of Delaware (sometimes referred to
herein as "Chilton" or the "Reporting Person").

Chilton is the general partner of certain investment limited partnerships (the
"Chilton Funds") and the investment adviser of certain managed accounts (the
"Managed Accounts" and, together with the Chilton Funds, the "Client Accounts"),
certain of which own Common Stock of the Issuer. As such, Chilton exercises
voting control and dispositive power over such Common Stock. Chilton's Client
Accounts are primarily engaged in the business of investing and trading in
securities.

The address of the principal office of the Reporting Person is 1266 East Main
Street, 7th Floor, Stamford, Connecticut 06902.

During the past five years, the Reporting Person (i) has not been convicted in a
criminal proceeding (excluding traffic violations or similar misdemeanors) and
(ii) has not been a party to a civil proceeding of a judicial or administrative
body of competent jurisdiction which resulted in a judgment, decree or final
order enjoining future violations of, or prohibiting or mandating activities
subject to, Federal or State securities laws or finding any violation with
respect to such laws.

ITEM 3.     Source and Amount of Funds or Other Consideration.

As of the date hereof, Chilton has acquired on behalf of its Client Accounts
10,359,756 shares of Common Stock for an aggregate purchase price of
$134,864,304. All of such purchases and sales were made through open market
transactions. The funds for such acquisitions came from the working capital of
the Client Accounts or from their margin accounts in the regular course of
business.


ITEM 4.     Purpose of Transaction.

The investment in the Common Stock by Chilton, on behalf of its Client Accounts,
was made in the ordinary course of its business of investing and trading in
securities, as reported on the Schedule 13G. Chilton acquired the Common Stock
believing such securities to be undervalued.

Chilton intends to continue to review on a regular basis its investment in the
Common Stock and the Company's business and affairs, as well as the price level
of the Common Stock, conditions in the securities markets and general economic
and industry conditions. Chilton may in the future take such actions with
respect to its investment in the Common Stock as it deems appropriate in light
of the circumstances existing from time to time, including acquiring or
disposing of Common Stock at any time and from time to time in the open market
or otherwise, and communicating its views regarding the Company to third
parties.
