Does anyone have any advice to help me get better at breaking the ice?

So I love going out a lot - I'm at a university in Sweden, I go out to bars or to rock and metal concerts constantly, clubs often too (my excitement for clubs depends a bit on the music because I really only like rock and metal music). I'm very comfortable going out to these places/travelling by myself, but I also love socializing with other people. Except my way of socializing is hoping someone else finds me interesting enough to talk to and coming up to talk to me.

This isn't entirely unsuccessful, because I do have quite a lot of friends and people often do talk with me when I'm outside but I'd also like to start initiating more conversations myself without entirely relying on others if that makes sense lol, and I believe it would also help me get better at carrying conversations. I'm also shy to initiate conversations with people who add me on social media and any advice to help with that would be really helpful too.
