In camp, my mates and I had our own computers, so we either
copied the songs onto the hard disk or played straight from the CD
That was until a few virus attacks occured (not
started b any of us) and our CD drives and USB ports were
disabled.
After that, I simply brought my old discman along and hooked it up
to the monitor speakers. They were better than the in-built ones.

I had my whole collection in there: U2, Coldplay, Crowded House,
Red Hot Chili Peppers, Nat King Cole, Bossa Nova, the Bee Gees,
Franz Ferdinand, the Rolling Stones, Jem, Katherine Jenkin, Oasis,
Rogue Traders, The Police... 
They weren't a hit with the others, but I didn't like the Scissors
Sisters songs they played either.
