Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE genre ( g_name varchar2(20), rating varchar2(10), most_popular_in varchar2(50) )
TABLE: CREATE TABLE song ( song_name varchar2(50), artist_name varchar2(50), country varchar2(20), f_id number(10), genre_is varchar2(20), rating number(10), languages varchar2(20), releasedate Date, resolution number(10) )
TABLE: CREATE TABLE artist ( artist_name varchar2(50), country varchar2(20), gender varchar2(20), preferred_genre varchar2(50) )
TABLE: CREATE TABLE files ( f_id number(10), artist_name varchar2(50), file_size varchar2(20), duration varchar2(20), formats varchar2(20) )

### Question ###
A bar chart about how many songs were released for each format?, could you list Y-axis in descending order?

### Accurate SQL ###

SELECT formats, COUNT(*) FROM files GROUP BY formats ORDER BY COUNT(*) DESC
