That’s just your opinion, man. I checked the site on iPhone and would say that it’s better than 80% of the sites I see. No performance issues at all. The extra wide font I don’t like however.
I discovered SomaFM channels (SomaFM, Secret agent, GrooveSalad) from iTunes Radio around 2003. Listened to it always while working on my computer while studying in university. Good memories and so happy they are still around!
