I see that the Yamaha WXC-50 streamer has a USB input on in that I assume can be used to play MP3 music files. This might be ideal as there won't be a ton of music required and sound quality should be decent but not necessarily pristine. Bluesound sounds nice but may blow the budget.

Is there anyone that has integrated with Musiccast? I want to know if I can create an ipod like interface to select through say 100 songs. I'm imagining a starting menu on the RTiPanel that starts with two buttons - one for yoga instructions and another for music. The customer should be able to dive into the selections like an iPod. The only other buttons I would have are transport and room volume buttons.

Want to use an XP3 processor and possibly a powered speaker with the preamp.
