For musicians, your obvious guess would be they love music. But the truth is there is life outside music and there is a lot that they can do to have fun. For musicians, there is a lot that they can do already with music. Some of the other activities that musicians can do to have fun include:
Do movies/Plays

Some many movies and plays are fun to watch and will keep anyone entertained. You just have to know your genre of interest and choose wisely. There are always plays happening at the cinemas. Find more about the storyline and the characters to know if it is your kind of play.
Reading
You can never go wrong with books. The best part is that there is a wide genre of books hence there is no limitation on the kind of books that you should read. Reading will not only give you knowledge but will inspire you and give you the experience of others. It will also entertain you and help you be more creative. The day we stop reading, is the day we stop learning and hence stop living.
Play games
There are plenty of games that one can do. With games at least you will be having fun while at the same time keeping your health in check. With games, it depends on your interests and skills. For example, if you are an outdoors kind of person, then outdoor games such as outdoor foosball would work better for you. If you are not sure, you can join a sports club then try out different games until you find one that you love.
Travel
Traveling is very important. You learn new things, experience new cultures and meet new people. With traveling, it does not have to be necessarily expensive for it to be fun. You can decide on a random road trip with friends or family and it will still be fun. If you want to go to your dream destination, however, you will have to save in advance and do your planning well. If you don’t plan on time, it may never happen.
Do art
Apart from singing, there are many other kinds of art. You don’t need to go to art school to do art. In the digital era, there is YouTube, Pinterest and many other sites where you can learn a lot of things and get ideas on what you can do. There are many DIY projects that you can explore depending on your interests.
Volunteer
Giving yourself as a service is a good way of having fun. You will be making an impact and putting smiles on other people’s faces while at the same time have fun. For some places, you don’t have to give so much of your time and apply early to volunteer. Just identify what areas touch you most then nail down on one area and start with that. That will help you choose something that you love.
