Also leaving Spain, making tracks (1-5)

I believe the answer is:

b-sides

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

'tracks' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'also leaving spain' is the wordplay.
'also' becomes 'besides' (I've seen this before).
'leaving' suggests deleting specific letters.
'spain' becomes 'e' (abbreviation for Espana).
'besides' with 'e' removed is 'B-SIDES'.

'making' is the link.

Can you help me to learn more?

I've seen this clue in The Guardian.
