error during lightweight transaction in Cassandra using java driver? - cassandra

Question

Here is my method to create table if it does not exists.
session.execute(
"CREATE TABLE simplex.songs (" +
"id uuid PRIMARY KEY," +
"title text," +
"album text," +
"artist text," +
"tags set<text>," +
"data blob" +
") IF NOT EXISTS ;");
session.execute(
"CREATE TABLE simplex.playlists (" +
"id uuid," +
"title text," +
"album text, " +
"artist text," +
"song_id uuid," +
"PRIMARY KEY (id, title, album, artist)" +
") IF NOT EXISTS ;");
}
when I run this, I get the following error:

Wrong syntax:
CREATE TABLE IF NOT EXISTS keyspace.table(columns ...)
