Anyway, ...
Consider the analytic sum() function. Here is an example you can adapt to your needs - the COUNT() I am using is similar to the SUM() you need
select distinct cd_id, count(cd_id) over (partition by cd_id)
  from m_cd_tracks
order by 1
CD_ID   COUNT()
1     34
2     32
3     32
4     32
5     30The analytic COUNT() is similar to the GROUP BY COUNT() but it returns every row. DISTINCT eliminates the duplicates. The OVER () clause allows the PARTITION definition which defines the group. You can read all about the analytic functions in the online documentation.
