Save the song as an audio file and upload to SoundCloud (or somewhere else, as long as it can be downloaded/played from a url).

Was looking to enter a song where exactly should I be looking to put it is soundcloud a free option ..?

Soundcloud has both free and paid options.

PGMusic also has a 'Radio Station' where they feature BIAB songs on Soundcloud.

I use the free option of Soundcloud and the free version is sufficient for all my needs.
