Well, at least your 'VLC' question is starting to make some sort of sense!
Here's part of your answer:

However you'll still need somewhere to host the actual file. While there are hundreds of offers of free web space available, the providers nearly always offer such space solely for websites (rather than for MP3 files) because they want to append their advertising. Finding somewhere for an MP3 file might not be too easy.
However you've almost certainly got some free web space available anyway. Almost every ISP offers free web space to its users. It's intended for your own website but most ISPs will let you host single files there as well.
Tell us which ISP you're with and we'll try to tell you how you use your free web space to upload an MP3 file (via FTP).
