What would be the best way to upload my music onto my website?

building a real website with .com or your domain name

is like having a physical store

3 steps you need to complete

1. find a physical store (find a server/virtual host)

you may rent or do it by yourself or but it

Rent-means you need "virtual host" (search engine can help you)

Do it by yourself - find a computer and set it as a server

2. put your commodities in your physical store (uploading your contents to server)

Web contents are placed to the server(photos or texts or music)

any function you need can install in this stage

set upload system in this stage that you may easily upload your music

3. name your physical store (domain name setting like www.tsmmc.com)

let visitors can link to your website by setting DNS server

you may set such server by yourself

try outsourcing of it - you will save a lot of time
