LedokolMP3Search, formally MP3 Search, are the sister site of GoMusicNow. Both sites recently had name changes, which seems a little bit suspicious. Both sites are also terrible at what they do. The sites are rarely updated, they have awful customer service and they only offer 210,000 mp3 tracks to download.
Other sites offer a lot more music and a much better service. My recommendation is to use another site instead.
