Hello again!
As a byproduct of the work I am doing, I began an audio player [software], using wxWidgets and C++ [same old,same old] plus an open source cross platform library named Audiere . Using that it will be able to play Ogg Vorbis, MP3, FLAC, WAV [uncompressed], AIFF and some other quite uncommon formats like MOD, S3M, XM and IT.
Not a lot of work is needed, from where I am already. But I would like to implement a feature so that the player is able to retrieve the lyrics [based on the files tags], from online sources, displaying them while the song is played.
Here is a screenshot:

Other main features would be, all-in-one window interface, multi playlist handling,no needed installer, lightweight and a small implementation of a media library.
I am not sure about the Transcode [tab on the picture], but if its not that, it will be a tag editor.
