Components is the main reason why I use foobar2000 on pc. The ability to play non-standard audio formats and ability to choose which formats you need to play makes this player unique and preferable.
I've been using Droidsound-E on android, as it lets me play most of game consoles audio formats, but there's no such thing as "component", all plugins for playing audio formats are already preinstalled and that's why this app is somewhat heavy.
Well, that's what I'm asking for - add a component functionality for your mobile app.
