My daughter used to ask for specific tracks as gifts. Painful as it was, because I'm encouraging her love of music I always listened to each one after downloading it before passing them on if suitable.
Then she started to ask for albums by certain artists and so I vetted those. By this stage I felt a bit like GCHQ but even checking 12 tracks at a time wasn't too much effort.
Having seen it at the petrol station she recently asked for "Now...98" for her birthday. That'd mean I'd have to check out 46 tracks before I could let her have it.
