Reply to Ableton Song Size

Hey, I don't mean for this to be a shameless plug for my song, but I have a legit question. I made a dope mix (Save The World or Leave It Behind) in Ableton, but it is 100 MB. I have no clue how to make it smaller without compromising size. Any Tips.


And in case your cusious how it came out :
