Muve Music, the unlimited music plan offered by prepaid cellphone company Cricket, now has 200,000 subscribers.
The milestone announced Thursday makes it the clear No. 2 in the subscription music category behind only Rhapsody.
Cricket, a division of Leap Wireless International Inc., also announced Thursday that it would begin offering the service on Android-powered smartphones by the end of September.
Cricket's music service has posted rapid growth since first being unveiled in January. Muve had 100,000 subscribers by early July. Rhapsody, which has been around since 2001, has around 800,000 subscribers.
