Spotify Hits Play Button: Hot Trends

NEW YORK (TheStreet) -- Popular searches on the Internet Wednesday include Spotify on news that the digital music service is moving beyond Facebook and opening itself up to all Web sites.

Spotify announced its Play Button Wednesday, which is a widget that can be embedded onto Web sites -- making all of the songs it has licensed available to anything from blogs to news sites. The Spotify Play Button will be free. Web sites belonging to the Huffington Post, Tumblr, People magazine and Rolling Stone magazine are already adding the service.

Spotify said it has about 3 million subscribers. It is currently converting over 20% of its users from its limited free service to subscribers who pay for unlimited access. The company is still looking to raise funds at a valuation of up to $4 billion.

Wells Fargo(WFC) is trending after the National Fair Housing Alliance said it filed a federal housing discrimination complaint against the bank.

After surveying more than 200 homes in various cities, the alliance accused Wells Fargo of maintaining foreclosed homes in predominantly white neighborhoods better than it did in minority neighborhoods. It alleged that bank-owned homes in white neighborhoods were 33% more likely to be marketed with a professional "for sale" sign than homes in minority communities, and were treated in a "far superior manner."

Wells Fargo said it disputes the claim and conducts all lending practices fairly and consistently without regard to race.

The federal Fair Housing Act stipulates that banks, investors and other parties must maintain and market homes without regard to race or ethnicity.

Yum! Brands'(YUM) Pizza Hut is another popular search as the food chain has unveiled a new pizza with a hot dog-stuffed crust.

The large 14-inch pizza, which features a giant hot dog folded into the crust with a "free" mustard drizzle, has only been introduced in the United Kingdom. It's currently only available for delivery, but is expected to be offered on in-house menus in time. For now, Pizza Hut has no plans to bring its hot dog-stuffed crust pizza to the United States.

Thailand and Japan were the first countries to sample the unusual pie.
