Feedback for logo's

During one of my lessons i decided that i would get feedback from other members of my class on what they think of the three different logo's which i had designed for the free different radio station, i gained both positive feedback as well as negative feedback. some points which my peers had made was:

Buzz: 'i like the little buzz symbol just below the B'

'did it have to be a black background?'

'i like the lines buzzing off, it shows a lot of energy therefore linking with the name'

Pulse: 'same with the splatter its effective but i don't understand why you have chosen it for pulse'

'i like the choice of colours they don't single out a specific gender'

'creative and colourful i like the font and think it will suit the target audience'

Shred: 'the green splurge is a nice effect as it makes the letters almost pop out'

'now this symbol is great, perfection but it is similar to the buzz logo with the colours which you have used'

overall i received one Even better if and this was; ' you had a symbol on each logo linking them together'

after reading all of these feedbacks i believe that my logos will be successful in reaching the audience which they are targeted at; however i think i would also need to add maybe a icon or something which would make the logos look more like a 'family' as i've only got the font type the same on each logo.
