Leaving Italian?

Two years of Italian classes ( a lifetime ago ) in university have left me with the remnants of very rudimentary language and this has become somewhat problematic as it is now cutting into my singing along to the songs I have redicovered which were originally recorded in Italian. There is no way for me to effect the necessary pronunciation without hundreds of run throughs and frankly my singing voice sucks so that option is imperfect at best. Despite the fact that I love to sing regardless of the off key notes I seem fated to produce, the bad accent is yet another worrisome part of this vocal mess. I am not about to take Italian lessons anymore than I am prepared to take singing lessons which leaves me back where all this began. The only solution that I think I can live with is to become a 'hummer'! If this is my chosen path it will not matter at all how much I seem to be able to butcher a romance language, nor will I need to listen to my off key self in a way that is sure NOT to be music to my ears.
