Hi all,
i have all sorts of sounds / music playing in my head in the day. Sometimes it's a well-known song that's 'stuck' in there 
But generally i'll 'hear' myself running a riff or a bassline in my head whilst making dinner, for instance. It's something I've never heard, but if it 'stays' long enough (it usually morphs into something else) i'll get to the computer/keyboard in an attempt to record it.
Anyway, does anyone else have this... uniqueness!??
