Conversion question

[Draxxx]

First up, Love this! Thanks Dev! <3

So, I have a question relating to file conversion; If I set the DOWNLOAD_FORMAT to mp3, and DOWNLOAD_QUALITY to veryhigh (320),
Is there actual file conversion done? I see the "[...] Converting file..." message, but thought that if I download the file in the required format, there would be no conversion done.
If there IS file conversion being run (MP3>MP3), Is there any way of downloading lossless files, like FLAC or WAV?
Or can the coversion be skipped if it's already in the desired bitrate?
Thanks again!

EDIT: So I can see this bit of code in track.py (at line 304)

download_format = Zotify.CONFIG.get_download_format().lower()
file_codec = CODEC_MAP.get(download_format, 'copy')

So I assume it's just copying the file, and that the "[...] Converting file..." message is just in lieu of a 'Copying' message..
