When you render try the ABR(Manual) default setting of 64/320/128k. This will keep a low bit rate and reasonable quality and size but will lose some. This track was rendered at this as an example, around 4 mins and 4 meg. This will play on all my media players with no problems and I've not found a web based one that has problems playing it. Note:The quality of sound will be dependant on how the original tracks were recorded and EQed and treated and raising bit rates will not improve a bad recording. HTH :)
