where's my theme?

Where?? FWIW, any theme can be modified to look any way you want — you don’t need one labeled by someone else.

Themes appear in Appearance > Theme
Or do you mean something else entirely?

You can try Unsigned theme. This theme is ideal for musicians and bands looking to showcase their music, tours, photos, videos and band members.

Cheers.

Did you submit a music theme to the Themes Directory on www.remarpro.com and it’s not showing up?
