I found a LEGIT site, giving away Spotify Premium Codes daily. They also have Gamestop Gift Codes, Microsoft Codes, Minecraft, PSN and MANY others!
They also have a integrated FORUM!
I have got around 3 Spotify Premium Codes in the last 2 days.
Most of the rewards cost 10 points, you get a point for every visitor that use your refferal link. No stupid surveys!
When i was done I got this on my screen: https://www.spotify.com/code/Y2T5LW4mYP
I went on spotify and redeemed it right away, and BAM! I got 3 months of premium!

Have fun and ENJOY!
