Owned by iHeartMedia, the station carries a Spanish-language format featuring a mixture of Latin pop and English-language adult contemporary hits.

In the later years, however, due to the increasing amount of R&B and Adult Contemporary music being added to the playlist by Broadcast Architecture (which WLVE adopted in 2007), the ratings started to decrease drastically.

[15] In 2010, WMIA-FM began adding more pop titles from artists such as Maroon 5, Michael Bublé, Kelly Clarkson, and Taylor Swift to its playlist, following a pattern used by sister stations such as WWVA-FM and WISX which eventually evolved out of, or switched from rhythmic AC, as the station became more hot adult contemporary.

While there were rumors that the station would flip to adult top 40 after the holidays, the rhythmic AC format returned on Christmas Day 2010, at 11:58 am, with "Material Girl" by Madonna being the first song to be played.

By June 2012, BDS has moved the station to the Top 40 panel due to its increasing amount of rhythmic pop product, although this was done to complement sister station WHYI-FM, who is the market's primary Top 40/CHR outlet, and to a lesser extent, to shift the older 1980s, 1990s and 2000s product to adult hits sister WSHE.

It also adopted an adult top 40 presentation, using the same approach as sister station WKTU in the New York City market,[16] and in early 2014, changed slogans to "Miami's Variety from the '90s to Now".

This put WMIA-FM in a crowded field for adult music competing between WFEZ, WLYF, WFLC and WRMF.

[23] On November 24, 2023, at Noon, WMIA-FM relaunched as "Magic 93.9"; the station focuses on Latin pop and English-language adult contemporary hits from the 1980s and 1990s (with its first song being "Conga" by Miami Sound Machine, and its playlist and promoted core artists including performers such as the Backstreet Boys, Celine Dion, Luis Miguel, Madonna.

[24][23] iHeartMedia's chief programming officer Tom Poleman stated that the format was designed to appeal to bilingual listeners "that love the big Anglo hits but want to be spoken to in Spanish", emphasizing "the importance of companionship in radio, how the elements between the songs are our unique proposition", and that a "Spanglish" presentation would not have had the same cultural impact.

[24] The station launched with a full airstaff, with the most notable member being Humberto "El Gato" Rodríguez, formerly of WZTA and WRMA, in mornings.

[23] "Magic" proved more successful, with its December 2023 ratings increasing from 15th place to 6th among adults 25-54; Poleman credited word-of-mouth as having been a factor alongside the company's own marketing.
