I'm trying (so my husband tells me ) to download a track but all the sites i find say mp3 download, can i save this to disc and play it in my car like i would a normal cd? or am i being an idiot? Please help!

Evening all, just to introduce myself cos i'm new well sort of... came on here to plan my (dare i say) wedding. It's all changed. Trying to get used to a new laptop and it's a nightmare anyone watching the talent thing?
