Congratulations to a talented, tightly-knit team of founders. It's rare to find four people who have such great synergy and single unified direction. They have a great mix of design, engineering and marketing among them and the fact they are so in love with music coupled with this round of financing tells me the Listn app will keep growing.
I had the pleasure of going through FounderFuel at the same time as the Listn folks - they aren't the type to base their positioning on comparing with other services. I think it's safe to say they only used the X to Y connotation for its great subject line value.
