Hive does not have an algorithm as such. You have to build your followers and/or make use of communities to get seen. There are some music contests too.
Some people are not so keen on Dtube as they had a split with Hive after getting lots of support. I think some of that was down to personality clashes, but then we have some strong opinions here on how things should be done.
I think there is potential to build up Hive as a place for musicians. It has some unique features that means fans can support and artist without directly sending them money. We also have the @risingstargame that is built around music and musicians.
Have fun.
