My English Diary: Day Thirty-One

Last week I had been was partying in at a bachelor party. I went with my best friends to a fabulous folk fair in a city called Albacete, which is around a two hours driving by car drive from our hometown.
In At this fair, people merely drink, eat and dance. The music starts more or less at around 12:00 noon and doesn't stop until 07:00 am in around 7 the next morning!
The prices cost of food and drink are is very cheap., You can take get a mojito cocktail for three Euros or a beer for one. Sausage sandwiches Hot dogs (although could be sausage sandwiches and not hot dogs but fairs usually have hot dogs) costs fewer less than four Euros.
I've never seen so much many people dancing together, I hardly highly recommend/commend it to everyone anyone who wants to enjoy an authentic Spanish popular party.  It is better than Pamplona's San Fermines or the Valencian Fallas.
The songs more played most often were "Balada Boa", from the Brazilian artist Gustavo Lima, and Pablo Alboran's hit "Volver a empezar".

Good effort just remember your capital letters for Proper Nouns.

Last week I had been partying in at a bachelor party. I went with my best friends to a fabulous folk fair in a city called Albacete, placed about two hours driving by car from our hometown.

In this At the fair, people merely drink, eat, and dance and merry-making. The music starteds more or less around at [12:00am or pm? Better to use "midnight" or "noon"] and doesn't not stop until 07:00 am in the next morning!

The prices of food and drink are very cheap. One can you can take get a mojito cocktail for three euros or a beer for one. Sausage sandwiches [hot dogs?] costs fewer than four euros.

I've never seen so much many [people are countable nouns] people dancing together. I hardly highly recommend it to everyone anyone who wants to enjoys an authentic Spanish popular party., It is better than Pamplona's San Fermines or the Valencian Fallas.

The songs more mostly played were "Balada Boa", from Brazilian artist Gustavo Lima, and Pablo Alboran's hit "Volver a empezar" with my favorites, "Balada Boa" and "Volver a empezar" respectively from them.

The way you wrote means that the most of the time the party played only these two songs.  I think you wanted to say the party played mostly the songs from these two artistes.
