Can you add support for saving the title and artist of the current artist song playing (eg. Tunewiki has the ability to email this info).

Good news for you ;) We have had the tagging feature way before TuneWiki ;) If you like a song press the tagMe button on the player. Once you do go to your tags. Long press a tag item and you will be provided with a few options. There you can click share or you can click edit and press copy tag to place it on the phones clipboard so that you can paste it anywhere you need.
