It sounds like you're getting ready for a music-related activity tonight, and you think you might have some time to practice or learn songs for it. The tweet from @punkstr suggests that they're planning something at 19:30, but you're not sure what it is yet. You're thinking about using the next two hours to get prepared and feel more confident with your music.

As you wait for more information about the plans, you're trying to stay positive and make the most of the time you have available. The hashtags #musicstr and #punkstr suggest that tonight's event will be related to music, possibly punk rock.
