If you're a music buff, you can earn a few pounds doing the thing you love. The SliceThePie website lets you earn money reviewing music as an online 'scout'.

You'll review random anonymous tracks, and be paid for each one. The downside is, you can't choose the songs - or even the genres - you want to listen to.

Time spent? As much or as little as you want.

Money earned? The pay is poor (typically 5p-25p per song you review), so this is only for those who'd enjoy it as a hobby anyway.
