Add another to the mystery that is 7000 kHz:
4/26/12, 7000 USB, 0200z (approx): Via east coast web tuner and home, besides the usual sideband chatter in Spanish and Portuguese, occasionally hearing music. Only song I could identify sounded like Boston "Amanda". Lots of tone beep QRM, not CW, and between the intermittent music, sideband chatter on both LSB and USB, and the QRM, it sounded pretty much like a typical day on 14275 and 14313 USB and some 75-80m freqs.
