MP3City sports a catalog of mainstream music and prices of $0.20 per track - regardless of the length of the tune. They accept VISA, Mastercard, e-Gold and Webmoney as payments and provide the usual click-to-download web interface.
The catalog seems similar to other websites I've reviewed ( GoMusic and MP3Search come to mind, read those reviews here and here respectively ). Like many sites, some older tracks are found at lower encoded bitrates, but newer tracks are always at high bitrates (192kbps - 320kbps).
