I'm new, so apologies if this has already come up, but I haven't seen any mention of www.firstlook.com as a point-earning source.

For rating music and other streaming clips, you rack up points (125 per day) that can be redeemed for various prizes; 1 point is worth about 1 cent.
No travel awards yet, but in 16 days, you can earn a $20 gift certificate, which isn't too bad. The site seems very reliable.
