Solved
I added :join_table option=>"" in both models and changed
====== _user_settings.html.erb
......
<% f.fields_for :habits_and_past_attributes do |habit| %>
......
<p>
<%= label("user_settings[habits_and_past_attributes]", "music_ids" ,
"Musics") %><br />
<% Music.find(:all).each do |music| %>
<%=
check_box_tag("user_settings[habits_and_past_attributes][music_ids]
[]","#{music.id}",false) %><%= "#{music.display_name}"%><br />
<% end %>
</p>
......
<%end%>
