Is it referred as to something else? Like my version of a song or tribute.
If you play and sing it yourself, then it's a cover. If you merely use editing tools to change it around, then it's a remix. A remix generally doesn't include a new performance or recording, it's merely editing and changing what has already been recorded.
A cover is a new recording or performance of a song written by someone else, or sometimes it's a new recording or performance of a song originally performed and/or recorded by someone else, regardless of who wrote it.
A tribute song is an original song, likely in the style of the band or artist that it is a tribute of. A tribute band is a band that performs and/or records several covers all originally written/performed/recorded by the same band. Tribute bands usually also dress up like the bands they are tributes of, and may even replicate stage elements, etc.
Note that covers and remixes require a license from the copyright holder or else they are usually infringing on that copyright. For a live performance of a cover or remix, smaller venues often pay a blanket licensing fee. For larger venues, the act performing the cover (you, in this case) may have to pay the fee directly. Copyright holders can refuse to license their songs for public performance (if I'm not mistaken), but cannot refuse to license their songs for recording. This is called "compulsory licensing", which means you must be allowed to record the song, but the copyright holder can charge you a reasonable fee to do so. I am not a lawyer. Consult a licensed attorney before doing anything with legal ramifications.
