Ahh, as long as music doesn't get in the way of day-to-day life like the others have said then you are as free as a bird to listen to it.
I love my music and I never leave my house without my iPod touch or my ear phones for that matter.
I could say different with my music and I like Tokio Hotel, their music is great, and the just the songs they speak to me, some are mostly sad. But I love them and a really good band. Sorry I went off again! Forgive me.
