LOS ANGELES – Amazon.com Inc. this week launched a store that sells digital songs for 69 cents, an attempt to bring more people to its e-commerce website and bolster its plan to charge people to store tunes on distant servers known as the cloud.

It has cut the price on singles to 69 cents in the past, but this is the first time it has dedicated a page to the offering. About 200 songs out of the 15 million available have had prices cut to 69 cents.

On Friday, that included 26 of the top 40 songs, from artists such as Katy Perry, Jennifer Lopez and Black Eyed Peas.

Craig Pape, the director of Amazon Music, said cutting prices boosts music sales and improves the site’s music recommendation engine.
