Track records by home contents (5)

I believe the answer is:

epsom

I'm a little stuck... Click here to teach me more about this clue!

'track' is the definition.
(I've seen this before)

'records by home contents' is the wordplay.
'records' becomes 'EPs' (EP is a type of record).
'by home contents' becomes 'om' (I can't explain this - if you can you should believe this answer much more).
'eps'+'om'='EPSOM'

Can you help me to learn more?

(Other definitions for epsom that I've seen before include "English town, of course?" , "Mopes around in English horse-racing venue" , "track in Surrey" , "Racecourse near London" , "can have horses" .)

I've seen this clue in the Sydney Morning Herald.
