GoMusicNow, formally GoMusic, join the group of sites that seem to not give a care in the world about their customers. Golden MP3 and their sister site, LedokolMP3Search all seem to have a lot of trouble replying to customer emails. They don't respond to questions or queries and the site seems a little out-of-date compared to others on the web.
My recommendation would be to use another site instead, as there are at least three other sites that do a far better job than these guys.
