VLC for Android is a full audio player with support for a ton of video and audio file types, including MKV, MP4, FLAC, and OGG. Media junkies can access internet streams, DVD ISOs, and disk shares. There's also support for multi-track audio and subtitles. One minor caveat is that the app's gesture control is sensitive.
If you're looking for something that's genuinely free, Oto Music should be on your radar.

The whole thing clocks in at under 5MB for the entire app. It's small, easy to use, and supports a wide range of music codecs.
