I just compared the the iOS and Andriod player styles. (I've purchased the available iOS style-packs, styles are included in the android distro)
Both offer what appear to be the same 35 styles. (in the player function)
The list of styles that comes up on the song info screen (in the editor) can contain user described style names that are not available player function styles. I can write a song chart and label its style as "Funky Bluegrass". The player is happy to play it using any of the 35 available player-styles (none of which are "Funky Bluegrass")
