MP3Count is the replacement for the closed-down MP3Sugar. However, it is not a site I would want to use. They are very expensive compared to other sites on the web, with tracks at 18¢ each. That's twice as expensive at LegalSounds.
The site also has a very low track count. Compare this to sites like MP3xclusive who offer over 3,300,000 tracks and you start to realise that MP3Count really aren't that good.
My recommendation would be to use another site instead, as there are at least four other sites that do a better job than MP3Count.
