Subject: [PATCH 1/2] lyrics: detect MusixMatch blocking

we just look for the bad string in the HTML. this has the downside
that we may consider songs that have those exact lyrics (you never
know, really) may trigger this warning as well and we would fail to
fetch those songs.

we also fail if lyrics contain another magic string that seems to come
up when you do fill in the CAPTCHA after being blocked.
