MOUNTAIN VIEW, California (

TheStreet

) --

Google

(GOOG) - Get Report

is preparing to launch a new online music service as early as Tuesday,

The Wall Street Journal

reported, citing people familiar with the matter.

The service is

similar to one recently launched by Amazon.com

, the

Journal

said. In March, Amazon launched the Amazon Cloud Drive, an Internet service that lets customers store music and play it on their smartphones or computers.

With this move, Google adds to pressure on

Netflix

(NFLX) - Get Report

, which has been aggressively adding

new content deals

to enhance its offering to consumers.

Google is likely to announce the service Tuesday at its annual Google I/O developers conference in San Francisco, the

Journal

said, citing the people. Initially, the service will operate in testing mode, and won't be available to the public at large.

Google, like Amazon, hasn't secured licenses from the four major recorded-music companies, and is likely to include a system that functions much like a remote hard drive, the newspaper reported.

Users are expected to be able to listen to songs they have uploaded to the service in "streaming mode" but won't be able to download the files themselves. The service is unlikely to be tied to an online music store like Amazon MP3, which gives users the option of adding new songs to their music locker at the time they buy them, the

Journal

said.
