Deleting Sims 4 Cach Files PC Windows 7

I know this is probably a silly question. I understand to delete Cach files. My question is, is this just like Sims2 & 3 and do I delete them all? I have Cach, localthumbcach.package,lotcacheddata & cachestr. Should I be delting all of these or just a few? I'm hoping this will allow me to build again on community lots but also stop the loading music to continue on in game. Sometimes the music doesn't shut off and I have to reboot the entire game just to have this stopped. Thx in advance for any help on which cach files I should be deleting.
