Can you recommend an Android .mp3 player that supports ReplayGain, gapless, and album shuffle?

Can anyone recommend an Android music player app that supports:

- ReplayGain (should be able to select either album gain and track gain);

- Gapless play;

- Album shuffle?

By album shuffle, I don't mean shuffling the tracks within an album. I mean having a possibly large number of albums loaded, choosing an album at random and playing the whole album in order. Also note that an "album" might be an actual album but not necessarily; it could also be two or more consecutive tracks from an album, all movements of a classical piece, or a single track.

I wouldn't mind paying a few dollars for a decent player that supports all of the above features with .mp3 files (since that's almost entirely what my music library consists of).
