The Hogwarts alumni often go to karaoke together;
Ginny and Luna tend to sing sweet little indie love songs to each other. Everyone finds this really cute, and no-one can stop smiling.
Parvati and Lavender like singing pop from the late nineties, the Spice Girls in particular. They do have a habit of kissing each other on the cheek during love songs, which is followed by lots of cheering.
Ron doesn’t really know a lot of muggle pop music, but he does have a penchant for early Britpop. Hermione loves his singing voice, especially when he sings to her blushing and stammering the lyrics.
Seamus and Dean tend to get a little drunk and end up singing big power ballads and cheesy rock songs to each other. Their particular favourite is ‘I Believe In A Thing Called Love’.
Oliver Wood loves a bit of Queen, with his favourite being ‘We Are The Champions’. He usually ends up drunk-calling Charlie Weasley afterwards to talk random Quidditch facts.
Draco has got into a habit of seeking ‘The Seeker’ by The Who to Harry. Harry cannot stop laughing when he does this.
Neville’s rendition of ‘Wonderwall’ is a universal favourite of the Hogwarts Alumni. There is never a dry eye in the house by the time he’s finished singing.
