Music Services Stream Into Crowded Field - WSJ.com

From a music streaming market dynamics snapshot

"Dozens of companies—from household brands to music-focused startups—plan to begin offering new services in 2014, according to companies that they have hired to help launch and operate them. [...]

Next year's models will feature more genre-focused services, which can bring down the subscription price because of the narrower catalog.
A niche service could charge as little as $2.99 a month, while others might allow fans to subscribe for just a week at a time. Some may offer discounted access to music catalogs by not including new releases, said Frank Johnson, chief executive of MediaNet Digital Inc., a Seattle company that will help bring more than 50 new streaming services to market next year."
