Is it really tinnitus, or can you just not get their music out of your head? Can't help you with the first but if it's the latter go on Youtube and type in Tinnitus - there are some techniques now that can eliminate it with a simple fix.
Should I put in the usual medical disclaimer? Naw...it's simple and can't hurt...may help
I used to follow a musician called Al Matthews - he played with Jericho, a local T.O. band and they had a beautiful ballad called. Make it Better (Than It's ever Been Before) and another rocky single called, Don't Turn Your Back on Me. I can't get those songs out of my head and it's been years. He offered to make me a studio copy - should have taken him up on that offer :)
Thank You, will try. Hate waking up to the same sound every day!
