Your personal choice of music will be what determines your top ten favorite songs however this does not stop every single radio station, music TV program and other music festivals from creating their own top ten. The fact is that most radio stations that use their listeners to vote for their favorite songs to rank the top ten are able to cast as many of their own votes as they like so that any particular song fits into the number one spot.
If rock, pop, rap and hip hop are not your favorite genre they listening to a commercial radio station or popular music TV show will not really give you any indication about what is hot in your line of good music. The classics, jazz, opera, blues, symphonies and harmonies or the tenors can all be found in different places to see what is still doing well or if anything new has come along to the scene. There are several different ways of finding out what is going to be on top through the internet, music festivals and other alternative newspapers.
The top ten songs on the radio in Japan would certainly be different to the top ten in Russia as would theirs be different again to the Americans. They might have several of the same songs in them and the chances of the number one song being universal is quite good however no matter where you are from there is always going to be a different kind of music that only you will enjoy on that personal level.
