Hmm, this is probably some obscure meaning of 'dead easy' ;-)

Even without DSP I wouldn't call gapless playback (or crossfading which is similar problem) to be dead easy.

On tablets this is further complicated by DSP doing both mp3 decoding and playback inside one black box. So you can't decode next song in advance without playing it and also most probably the mp3 dsp task does not allow concurrent usage anyway so you can't use it at all while first song still plays.
