Most amps have a 'aux' input that can be connected to a 'line' output from a computer. If you have laptop with a 'line out' socket then simply put a wire between them. The usual problem is that modern laptops often don't have a line output - only a headphone socket, or a headset socket - which incorporates a microphone. A headphone socket may work - it won't damage anything to try it. If not you need to add a external USB 'soundcard' with a line output - maybe £25 for a cheap one.

If you only have a desktop computer, and it's not close by, then things get more complicated. There are solutions involving bluetooth and wifi - but they can be tricky to get working. Burning a CD is probably easier. Last time I estimated - some years ago - I reckoned a CDROM cost about 8 pence.
