Minus to the song or reading rap, I mean what is called a minus to the song.
Edit: I specifically found for you, so that I do not spoke your own words. So I think it’s clearer: explanation (Wikipedia): “Minus phonogram (“minus”; “recording minus one vote”) - recording a musical work that does not have one or more parts, usually vocal or solo instrument. Under such a recording, a musician (professional or amateur) has the opportunity to perform the absent part himself. Most often this is just a ready accompaniment for a soloist. Also, minus phonograms are often used as the basis for creating independent compositions in the style of hip-hop and rap. Sometimes the minus tracks are simply listened to as instrumental music”.
I lacked in your track, a variety of instruments or musical instruments (for example, which are different though small musical deviations, transitions, etc. (if you understand what I am talking about) so that it is not so boring (but I marked that this is just my opinion).
The mood of the track is pleasant to the ear in the totality and harmony, a combination of tools in the arrangement and also so that someone wants to buy your track. For example: I am a buyer and went to your page with a track and what do I hear? “I want to buy this track right away”. It is this. I mean the audience of buyers, for which your track could be suitable for their video projects in commercial terms (because I liked your track by mood)!
The mood of each track is different, I can not explain it to you in words, it is necessary to listen.
Well, you should understand what is in demand here and in this market. But you are not obliged to write (make) your tracks in exactly the same way as top tracks (you should not copy, imitate, etc.), this is just an example for you.
