We recently purchased the 100 Hits Presents Karaoke sets from DMG Music in the UK.  It is a great set with excellent quality.  It is much less expensive if purchased directly from the UK. UK licensing is much more lenient than US allowing them to put the set out at a better cost to you the end user.  They can not distribute it in the US, so we have set up this store to allow you to buy it in the UK with several other excellent sets!  We got 1600 songs for under $160 shipped!  That is the best value we have found in recent years!

Put in your amount after the £ sign and there is your price!
