As an artist, how can I specify more then one genre to a song?

Examples:

folk, experimental

blues, rock

Thank you!

Currently you can only specify a genre eg folk, blues etc and then, if you wish, a sub-genre of the main genre eg for blues you can pick chicago blues, delta blues etc. You can't mix and match the main genres together.

Thanks, that's what I thought! But have a look at the examples above: folk and experimental are not sub-genres of one another and so are blues and rock. How are they specified?

To expand on Alex's point, you used to be able to, but that was prior to sub-genres being introduced, so there are relics of the previous genre listing, which is why the examples you listed have multiple genres.

I see. Thank you!

Thanks for making that clearer for Staraya IOS :) I'd forgotten about the previous genre listing system.

thanks for clearing that up ImOnlySleeping. you were right on the money.
