This is one of those “maybe it exists but I can’t find it” ideas. Something that I’d find very useful would be media player plugin that could use the ID tag from mp3′s (etc) to nip off to the WWW and find the relevant guitar tab so playing along is thus a very easy process. The idea could be taken further for different instruments, of couse, but it’s generally something similar to the usual “buy this album” button which is purely commercial. So, what’s out there, anyone know? If it doesn’t exist someone please write it!
