For a no frills player with useful features, I prefer Simple MP3 Maker. This is both a CD ripper and a player. It uses the LAME encoder for cd ripping (good quality), can rip to MP3, OGG, WMA and other formats. I've noticed little cpu load while playing or ripping. Includes a basic waterfall sound display. It has all the features I've ever needed to rip CDs and play back music. Best of all, it has no features that I don't need, download size is only 1 MB, and it is freeware.
