The Sound Room is a location in the Game Boy Advance game Wario Land 4. It is a place that Wario stores the CDs that he collects in the levels. Stored on the CDs are different tunes and sound effects can be played back. Each one has a unique album cover (refer to picture). Inside the Sound Room are two speakers on the wall, along with two television screens; one that shows the album cover for the CD Wario is listening to, and the other one shows a music video featuring a unique Wariogram (a human cosplayed as Wario), a dog, an apple, a fox mask, a raccoon, and many other pictures. Different colored CDs are stored in different rows. The first being green (retrieved from the Emerald Passage), red (Ruby Passage), yellow (Topaz Passage) and blue (Sapphire Passage). A sevententh CD, the Karaoke, can be unlocked by getting 10,000 or more points in every level, including Hall of Hieroglyphs and Golden Passage (even though there are no CDs to collect in those levels). It is a full song featuring a female singing in Japanese over a catchy tune.
