Shouldn't tribute songs be removed from the iTunes store?

Has anybody else noticed a sudden exoplosion in the number of tribute tracks now available for download from the iTunes (UK) store? They seem to have become prolific recently, with the majority being (in my opinion) poorly covered or instrumental versions of current chart tracks that are yet to be released. Not only this, but the album art and titles of these tributes can sometimes very closely resemble that of the genuine track, easily causing an accidental purchase if you're using the smaller screen on your iPhone. Perhaps I'm just bitter, as I have been caught out twice now.

The problem is particularly bad if, like me, you tend to tag the songs you like using Shazam or Sound Hound and then follow the direct link from the application to the iTunes store. If you're on the move whilst you're doing this, it's very easy to accidentally purchase one of these tracks in error. And you'd better be prepared if you've enabled one touch purchasing, as your selection of tinny and barely recognisable tribute tracks is about to increase significantly.

I'm interested to know if anyone else sees this as a bit of a scam? I'm minded to email Apple with a complaint but would value the community's thoughts so I can ground myself beforehand.

Thanks in advance.
