What is it called to buy a original song and record and also have ownership of the song and where to find places and list of websites that offer buy-able songs and also like in-and-around like how much does it cost? Thank You

This would be called buying the "Exclusive Rights" to the copyright:

Exclusive rights
Several exclusive rights typically attach to the holder of a copyright:

To produce copies or reproductions of the work and to sell those copies (mechanical rights; including, sometimes, electronic copies: distribution rights)
To import or export the work
To create derivative works (works that adapt the original work)
To perform or display the work publicly (performance rights)
to sell or assign these rights to others
To transmit or display by radio or video (broadcasting rights)

I don't know what country you wanted to buy it from, but here's a British
Web site with prices: License Music For Film, Television, Video Game. Music license. Music composer. License from music copyright owner. Copyright licence for your product. Commercial music use. Licenced and royalty free music.
