Music players like DoubleTwist are based on iTunes which supports very few ID3 tags. The ones supported are adequate for pop music but hopeless for classical music or even jazz. For example, in random play you may well want to keep whole compositions together, like a Beethoven Symphony with 4 movements and therefore four tracks. Again, compendium albums often have multiple composers so tagging (and displaying) the composer for each track is useful.
The Musichi software suite lets me tag my classical albums appropriately and has a player for the PC which takes advantage of the tagging. But there is no support for Android at this point in time.
Anyone know of a way I can do this?
