This boy that likes me, and I kind of like him, wants to hear me play piano.
I'm pretty good, but he's amazing.
What song suggestions do you have?
Not sure what you mean by "pretty good".
If that means "I'm practically a concert pianist but I'm just being modest", then do Hungarian Rhapsody, or La Campanella by Liszt. Maybe Rhapsody in Blue by Gershwin. Those are always impressive pieces.
If "pretty good" means "I'm better than average and I can play pop songs", try "All of Me" or "Waterfall" by Jon Schmidt.
