From your Radio Airplay account, look to the top right and click on the "Public Profile" link.
This will open a tab on your browser where you will see your Jango profile. From here you will see the song(s) you have uploaded listed underneath the player. Click on the "Play" button to listen to your upload and ensure you have added the correct file to your account.
To make any adjustments to your uploads go to your Radio Airplay account's ARTIST CONTENT > SONGS page. To remove a song, select "Edit Song" and choose "Hide". You'll then make room on your page to upload the correct file to your account.
You can also use a direct song link to listen to your files as well. From your Radio Airplay account's ARTIST CONTENT > SONGS page just use the Copy and share URL.
