I found this curious today. Cricket Wireless has announced a new feature called Muve Music. This is a music subscription feature, by which users do basically all of their music management from the phone (i.e. no sideloading).

Here's how Cricket describes Muve:

Muve Music™ is Cricket's newest innovation for the wireless industry marking the first time unlimited music is offered as part of a wireless rate plan. Muve Music is designed exclusively for the mobile phone so no computer is needed. Muve Music, delivered over Cricket's nationwide 3G network, includes unlimited talk, text and Web PLUS unlimited music downloads, ringtones and ringback tones. With Cricket's Muve Music rate plan, there are no download fees, no monthly music subscriptions, no streaming music to impact customers' data plans and no credit cards or contracts are required. In addition, Muve Music will have a robust catalog of music content including the four major record labels: Universal Music Group, Sony Music Entertainment, Warner Music Group, and EMI Music. Muve Music by Cricket will be available exclusively on the Samsung Suede in January 2011.
