Single vs Album View without iTunes

How do people organize their singles in 3.5? I am not using iTunes. In album view, singles appear as albums with their album covers. This looks great but I would like a view that looks like album view but only includes singles.

Also a view that shows albums without singles.

Most people classify singles the same way as albums because singles usually contain multiple tracks of the same song, just different versions.

Thanks bitracer, that makes sense. I also just found I can use the meta-field ‘Grouping’ to designate a track as a single and then set up a filter to just show those.
