I have a group of friends that would love to complete the survey but they are older than required. They reckon just because you are over 40 you don't stop listening to a station or enjoying good music.
Also maybe having the name of the artist/group next to the song title would save time downloading the music clip as there are often two titles very similar and if you are not on broadband it can take some respendents a long time to get the information. I know a lot of the songs but am unsure of the title at times.
Great surveys, great work and I loooove the rewards being so generous!
