I think any respectable player who has the ability to display lyrics should have an option to correct them!

Regarding the video support, my advice for the developers is to stay focused on the main purpose of this application! It's better to have a reliable and fully customisable music player than an application who can do many things but none at full capacity!
I think video handeling should be discused when there will be nothing to do regarding this audio player, when all the capabilities of a decent player were added!
And to be sincere, there are enough video players in development!
Still looking forward for:
- playing by browsing folders
- downloading cover by request
- equallizer
- repeat function
- even id-tag's editor
- landscape ui, for the car holders
....

This could be the best and popular audio player for maemo, like is winamp for windows. And not to remember all the winamp audio options. By the way... Thinking at winamp, the application can handle video files but it's not something desirable, it's more like a pain in the ***. A really valuable application should focus on a straight direction.
Audio Player - that must be the INSTINCTIV way!

Cheers!
